Detailed instructions for replacing the rear brake light bulb with your own hands

The brake light lamp performs two functions: protective and is one of the elements of the car’s exterior. The safety function is to alert drivers that the brake pedal is being pressed so that they can take appropriate action. Like any machine part, sometimes lamps require replacement. The article explains in what cases it is necessary to replace a car's rear brake light bulb, and also gives instructions on how to change it.

The brake light does not work - what other reasons could there be?

In addition to burnt out lamps, there are other possible reasons why the “stops” do not light up:

Wiring problems - broken wires or short circuit.
The fuse has blown.
Problem with the brake limit switch.

The fuse box is located in the passenger compartment on the driver's door side. Fuse number 3 is responsible for the brake light. Its rating is 10A, although some sources indicate 20A. In the picture below it is highlighted with a green circle.

List and ratings of some fuses

The limit switch is located under the brake pedal, its catalog number is Renault 77 00 414 986. You need to crawl under the steering wheel, feel for the limit switch with your hand and remove it the same way we removed the light bulb sockets.

What is a brake light for?

Recently, a brake light has become a mandatory piece of equipment for residents of Russia. If new car models that have come off production lines relatively recently are initially equipped with this device, then drivers of older cars are forced to install brake lights themselves.

The main task of the lighting is to inform drivers about the braking of the car that is moving ahead. Thanks to this, the motorist has various possible options for avoiding dangerous situations on the road. It is difficult to imagine how drivers could understand each other on the road when it is necessary to reduce speed or change lanes without warning lights. In this case, you would have to rely only on your driving experience, reaction or intuition.

What are brake lights for?

If brake lights or other elements of lighting equipment suddenly stop working, do not treat the problem with disdain. When driving a car with a broken brake light, the driver puts not only himself, but also other road users, in danger.

Without experience in testing car wiring using special equipment (multimeter), it will be easier to turn to a car electrician for help. But this is only in cases where you have eliminated the need to replace the brake light bulbs due to burnout.

What happened to the brake light?

Mostly it just burns out. There is nothing difficult about replacing it; it only takes a few minutes. There is no need to go to the salon, no skills or special knowledge are needed. But it is worth changing it as soon as possible. Not so long ago, all residents of our country were required to install a brake light, and while in new cars it was installed at the factory, in old cars the owners had to do it themselves. It is needed to let the driver behind you know that you are braking for a maneuver. This way he has time to stop too and you both avoid a dangerous situation. This is very important, but without it, both you and the driver who is driving behind you are in danger.

If your brake light bulb is burned out, you can most likely replace it yourself. There is also a less common reason - wiring fault. If you are not an electrician, it is better to see a specialist, but first make sure that the problem is not with the light bulb.

What is needed for replacement?

How to replace the stove tap on a VAZ-2109 yourself
Before changing the lamps, you need to prepare all the necessary tools and components. First, let’s decide on the choice of lamp, since it has the following varieties:

The power of the lamps comes in both 5 and 20 watts. There are no major differences between them, with the exception of the increased light output of the more powerful version. However, it is not worth it, since such lamps can easily blind the driver from behind, and energy consumption will only increase.
The presence of a base. The base contact system is gradually becoming a thing of the past with all its shortcomings in the form of poor fastening and loose fit to other contacts. Therefore, it is strongly recommended to install lamps without a base, if the design feature of the rear lights of your car allows this.
Glass color. If earlier this did not matter, then it is recommended to use LEDs with red glass. This is due to the fact that the increased light output of such lamps easily “slips through” the glass of the lamp and shines in a light color rather than red, misleading the driver from behind.
Availability of additional thread. Relevant for lamps that operate in two modes: brake lights and clearance lights. A striking example is the rear light of the VAZ 2101 car. Here you need to take into account the design features of the car. If it allows such installation, then you can safely install lamps with two filaments.

In addition to a new lamp, you will also need a tool kit, which should include Phillips screwdrivers and wrenches. All of them will be needed when removing the rear light.

Light Bulb Selection Options

The selection of products should be carried out in accordance with the technical parameters of devices already in use. Before changing light sources, you need to read in the technical documentation which products are allowed to be used specifically in your car. The best thing to do would be to take the burnt out light bulb and go to the store with it.

Products can be of several types:

The design of which has a base or without it. Basement options are not particularly popular today; their demand is gradually decreasing. This is due to disadvantages, such as the product not fitting tightly with other contacts, as well as unreliable fixation. So baseless light bulbs would be a better option.
The device can be equipped with two filaments or one.
The glass with which the product is equipped can be either dim or colored. If we are talking about incandescent lamps, then in this case there is no fundamental difference. As for diode elements, of course, devices in a red housing should be installed in brake lights.
Also take into account the power of the products, it can range from 5 to 21 W. The higher the power and detail, the stronger the light it produces will be. But keep in mind that too powerful devices can blind a motorist driving behind you, which can also lead to an accident. It should also be noted that more powerful products consume an order of magnitude more voltage.

Lamp selection

How to determine that it is time to change the wheel bearings on a Chevrolet Niva and how to carry out the replacement yourself?

Repair begins with a trip to the store for parts: you need to buy a light bulb. But before you go to the auto parts store for a new one, you need to determine which bulbs are in the brake lights on your Renault Logan. There is a two-filament incandescent lamp installed there, its name is Osram 7528 P21/5W

On its base there are two pins opposite each other, pay attention to this when purchasing - there are models where the pins are not on the same axis. It looks like this

But Renault Logan has a third, additional brake light: in the cabin under the rear window. It contains an incandescent light bulb with one filament, it is called Osram 7506 P21W. It looks almost the same, except that there is only one contact on its base and one spiral in the bulb.

To make the rear lights shine brighter, you can install LED lamps P21W and P21/5W. There are a great many of them on the market, and in this case, oddly enough, the rule “the more expensive the better” almost always works. Don’t buy outright “fawn” for pennies, good LEDs are expensive

Also pay attention to the direction of the lamp's glow. It should be omnidirectional, not oriented somewhere specifically

How to replace correctly

Now that you have already bought new lamps and are ready to work, let's figure out how to change the lamp in the brake lights on a first-generation Logan (sometimes they say first-phase). For simplicity and clarity, read the step-by-step instructions:

open the trunk;
We inspect the place where the headlights are mounted. It is covered with casing, but two plastic wings for attaching the headlight protrude through the cutouts. You can bend the trim, then you can remove the terminal block from the headlight before dismantling it;

Tail light and stop light

press slightly on the flask and turn it 90 degrees counterclockwise. The lamp will come out of the grooves and you can remove it;
install and turn the new light bulb all the way clockwise.

Dacia and Renault Logan have slightly different headlights, but the process for replacing lamps is similar.

On Logan in a new body

But when removing the headlight on the new second-generation Renault Logan, motorists have problems - they cannot remove the headlight, even though it is held in place by only one wing. Let's look at the differences. Let's start with the fact that Renault Logan 2 does not have a trunk trim in the area of the rear lights. The headlight is held in place by 1 plastic wing, a plastic guide and a “piston”, which is fixed in the car body. The fact is that after unscrewing the wing, the headlight cannot be removed. Experts advise doing the following: we do not unscrew the lamb all the way, and then we press on it with the palm of our hand from the trunk. From the outside, you need to firmly press the corner of the headlight, which is located closer to the rear door, with your palm and pull the headlight back. The palm should be clean and not slip, but rather stick to the headlight. Then the headlight will give in. In particularly neglected cases, they are removed into the gap between the body and the lamp using a wedge.

Replacing the additional brake light lamp

Let's figure out what to do if the additional brake light lamp does not light up. And on the Renaul t Logan it is located in the interior, but how can you change it correctly, since there is no access from above? The fact is that the lamp in it is changed from the trunk. To do this, there is a technological hole through which you need to stick your hand and turn the lamp counterclockwise half a turn.

In a station wagon

Renault Logan MCV or, as it is also called, Logan station wagon in Russia is produced under the name Lada Largus. Now let's figure out how to replace the brake light lamp on a Renault Logan Universal. Double-filament P21/5W lamps are also used here, and the lamps are held on two plastic nuts located vertically at the edges. They need to be unscrewed counterclockwise. Nut holders

Remove the headlight, but do not break the wires. After disconnecting the terminal block, you need to press the latch and remove the panel with lamps. As you can see, the replacement process is similar to those described above. Rear side of Largus headlight, latch at top right

In what cases is it necessary to replace the brake light?

The light source may either burn out completely or not work correctly.

In any case, in such situations the device cannot perform its primary function, no matter whether the lamp does not light up or blinks. When flashing, you should check the contact connecting the light source to the car's electrical network - it may have oxidized or been damaged

Before you start purchasing new devices, you need to make sure that the problem of the light bulb not working is related to it.

For what reasons brake lights may not work:

the safety element has burned out or the contact in its connection socket has oxidized;
the lighting source itself has failed;
there were problems with the rear optics activation mechanism;
oxidation of the contacts directly in the connector in which the lamp is installed has occurred;
the electrical connection circuit has been damaged or broken.

In this case, let's consider a situation where the problem lies in the lighting source - in order to change the device, you need to make sure that the problem is there. You will need to remove the lamp from the seat, and then install a light source from the turning lights or markers in its place. If, as a result of the replacement, you find that the brake lights are working, then, of course, the reason lies in the device itself. If the stops do not light up, then you need to check the fuses, contacts and wiring.

It should be noted that in some vehicles, when the lamp in one brake light burns out, the other brake light also stops working. Take this into account when diagnosing. Also, the need to replace lighting sources may be due to tuning the car. Initially, traditional incandescent lamps are installed in the brake lights, and when tuning, the car owner can replace them with two-pin diode products.

Why do car enthusiasts choose diodes:

due to their higher service life of about one hundred thousand hours, while conventional devices last about two thousand hours;
diodes have improved light output characteristics;
such products light up instantly, in less than 1 second, which generally increases the response time for the motorist driving behind you;
the performance qualities of diode elements are higher as a result of the use of an improved design (video author - Vyacheslav Igorevich).

What else could go wrong?

Not all cars have an additional brake light, because it is not required by law. This is for greater security, nothing more. If it doesn't work, follow the same principle, but prepare double-sided tape, try not to lose the rubber plugs. Otherwise, it's even easier because the extra light is usually not bolted on.

Replacing the Ford Fusion taillight brake light bulb: description, process

To change the brake light bulbs on a Ford Fusion, you will have to remove the tail light. The dismantling process is quite simple and does not require special knowledge and skills. The process is similar to the process of removing the rear light, but you also need to disassemble it.

Replacement video

https://www.youtube.com/watch?v=9bzu0lAJ6eA

The video will tell you how simple and easy it is to change the brake light bulb of a car's rear light, and will also tell you about the nuances, subtleties and tricks of the operation.

Removal process

Ford Fusion rear brake light bulbs tend to burn out. So, to change them, you will definitely have to remove the entire flashlight, since without this you cannot disassemble the body. To carry out this process, it is not necessary to visit a car service center, since the process of changing it yourself will take less effort and 20 minutes of time.

Let's get started with the process:

We remove the negative terminal from the battery, since the wiring operation will be carried out.
Open the tailgate.
We disconnect the block of wires, which is connected directly to the flashlight, with which we are going to carry out operations. Also, in the same place, you need to unscrew the plastic thumb that holds the flashlight.
Using a hexagonal star, unscrew the two fastening bolts of the lamp, which are located in the doorway.
We pull the lantern towards ourselves. After removing the bolts, the fastening is carried out by the pin from which we twisted the wing.
On the removed lamp, unclip the plastic latches using a flat-head screwdriver. And we change the burnt out light bulb.

Install the lamp in the reverse order.

Choosing a light bulb

To install a Ford Fusion brake light, lamps marked P21/5W are used. They can be either red or white light. For a more expressive glow, it is recommended to use untinted lamps. So, let's look at which lamps are suitable by manufacturer:

380 Red Standard Replacement 12V P21/5W Bayonet Bulbs (Pair)
Lucas 380 12V P21/5W Bay15D Stop & Tail X2 Bulbs
OSRAM Bulb 12V 21/5W Twin Pack Clear Motorcycle Electrics Lighting
Osram LEDriving 380 P21/5W 12v LED bulbs x 2
Bosch 380 P21/5W Car Bulbs x 2
GE 380 P21/5W Car Bulbs x 2
380 P21/5W 48* 2835 Canbus LEDs (Cool White/Amber) Dual Color
380 P21/5W White 60W CREE-XBD SMD 12*5W Canbus LED (2 Bulbs)
XTEC 380 12V P21/5W Clear Auto Replacement Bulb (Pack of 10)
380 ABD Prime 12V 21/5W P21/5W Bayonet Bulbs (Pair)

Of course, with modern trends, it is best to install LED technology bulbs, which are clearly visible in fog and other bad weather conditions. So, at night, the Ice lamp is better recognized than others.

Conclusion

Removing the rear brake light bulb from a Ford Fusion is quite easy and simple with your own hands. The process takes 15-20 minutes. It is also quite easy to select a light bulb according to the P21/5W marking

It is worth paying special attention to modern lamps with LED technology, which serve an order of magnitude better and have a fairly bright light

Removing and installing a rear light on a Priora

So, first of all, we open the trunk lid, and on the inside we find a special technological window with Velcro that needs to be opened. It is through this that you can get to the flashlight mounts.

It is worth noting that from the inside it is not mounted with bolts, but with special plastic screws that secure the lamp to the car body. There are three of them in total, of course, each of them must be unscrewed. After this, we move the lantern to the side from the outside, as is clearly shown in the photo below.

If it is necessary to replace the rear light, then each of the lamps should be pulled out of the light housing from its rear part. More on this below.

Why did the breakdown occur?

Most often you just need to replace the diode. But options are possible.

The contacts may have oxidized. Humidity, dirt, road dust - all this does not benefit the equipment. Wiring is damaged

Attention! If you do not have special education, do not fix it yourself, contact an automobile electrician. The mechanism connecting the brake light to the brake system has broken down. You brake, but the signal does not come on.

Use a tester to make sure the voltage is the same across different parts of the wiring. If the problem is already here, and you are not an electrician, just go to a service station. But this is rare, because the diode is the most fragile part and a simple replacement will solve the problem.

Replacement instructions

Before you change the bad bulb in the fog light, you need to understand how to get to it. The design of light devices built into the bumper varies and depends on the make of the car. There are 2 ways to access lighting devices:

from the wheel arch side;
by removing the optical block.

The first method is used when disassembling headlights of VAZ cars and other foreign brands with a similar design. For ease of disassembly, it is worth placing the car on an inspection ditch, although you can do without it. The work algorithm is as follows:

Secure the car and remove the front wheel from the side of the faulty device.
Unscrew the screws holding the plastic fender liner and remove it from the car. In some car models, you do not need to remove the entire mudguard, just bend it to the side.
Remove the rubber boot protecting the connector.
By pressing the corresponding protrusion, disconnect the block with wires.
Turn the burnt out lamp counterclockwise and pull it out of the block.
Insert a new element, secure it and assemble.

During the replacement process, try not to touch the bulb bulb, as sweat marks will reduce the service life of the part. If this happens, wipe the glass flask with a dry, clean cloth. Before assembling the unit, check the functionality of the lighting by turning on the fog lights.

Not all foreign cars allow access to the fog lamps on the wheel side. The question of how to replace burnt out light bulbs in this situation can be solved by removing the entire fog lights. You will need an inspection hole from where it is more convenient to unscrew the optical unit. If necessary, you will have to remove interfering parts - the lower apron or front body kit.

Remove the unscrewed headlight from the outside of the bumper and disconnect the connector. By turning counterclockwise, pull out the block from the block (this is done on Nissan cars), there are spring clips under it. They should be unlocked and the lamp pulled out. Having installed the new element and checked its operation by turning on the headlights, put the block and other parts in their places.

Feet

Dismantling

The main difference in the design of the crossover stops is the need to dismantle them when replacing lamps.

To do this, first open the fifth door, after which 2 self-tapping screws are unscrewed, which fix the element on the side in the door opening. Then, in the trunk, on the back side of the lamp, the decorative trim is removed, which blocks access to it.

This will allow you to unscrew the nut securing the stop. In this case, a wrench is not required, since it is a wing nut. It is made of plastic and screws onto a special threaded rod.

Next, according to the instructions, you just need to slide the flashlight back and remove it. However, in reality everything is a little more complicated. The attachment points are designed in such a way that they are at an angle of 90° to each other. Therefore, it is necessary to grasp the far edge of the flashlight and press slightly on it, disengaging the latch, then slide the element back and remove it.

Possible lighting malfunctions when braking

Continuing to drive when the Renault Logan brake light does not light up when braking, then you will expose yourself and other road users to danger, so periodic monitoring of the serviceability of these devices is necessary. Among the types of problems, the most common problems are:

When braking, one light does not light up;
When turned on, both brake lights do not light up;
The additional brake light does not work.

Since the operation of these devices is directly related to the vehicle’s electrical network, first of all they pay attention to its condition. It is necessary to check the serviceability of fuse F3, which is responsible for the power supply circuit for the brake lamps

The fuse circuit is installed in the interior block on the left side of the dashboard. Its power is designed to pass current up to 10 amperes. An indirect confirmation of its failure is the case when not a single lamp works.

You can check it by installing a known-good fuse or using a measuring device such as a multimeter or tester. If replacing it has not made any changes and the flashlight still does not work, then the search must be continued. The next step should be to check the condition of the machine's electrical wiring for broken wires.

The next element that you should pay attention to should be the stop lamp switch for the Renault Logan car. It is installed on a bracket with pedals

For better convenience when checking, it is best to remove the switch from the pedal bracket. This can be done this way:

It is necessary to disconnect the battery terminal, since the circuit of this circuit and the sensor are always energized;
The next step is to remove the connector with wires;
To remove the sensor from the installation socket, you need to rotate it 90 degrees around its axis and lightly pull it towards you. The device will be in your hands.

You can check the sensor with a tester in resistance measurement mode, or by connecting a known good one. To do this, connect the terminals of the measuring device to the connector of the switch and press and release its protruding rod several times by hand. The device must show serviceability, otherwise it needs to be replaced.

If the sensor has confirmed its serviceability, and the inspector is convinced that it is working, then you need to check the supply of on-board network voltage to it. To do this, replace the battery terminal and use the device to check its presence at the connector with wires. When there is on-board voltage at the sensor connector, you need to proceed to checking the rear lights and their lamps. Replacing it with a new sensor is carried out in the reverse order to its removal.

How to replace?

Easier than it seems.

Disconnect the wire from the light to turn off the power.
Unscrew the thumb.
Unfasten the mounting bolts with a Phillips screwdriver.
Remove the lamp. Sometimes they are secured with a plastic clip, sometimes they are inserted into a groove, depending on the model.
Unfasten the latches, take out the back of the lamp, and turn it over.
Unscrew the brake light bulb, install a new one, repeat the previous steps in reverse order.

Everything works - great. Doesn't work - you didn't check the wiring carefully or installed the light incorrectly. Try again. If it doesn’t help, go to a service station.

Replacement instructions

In general, the replacement process is quite simple, there is nothing complicated about it, but it is still better to look at the service manual and familiarize yourself with the electrical connection diagram.

Tools and materials

When all the necessary products have been purchased, you can begin preparation.

You will need:

a screwdriver with a Phillips head for unscrewing the bolts that secure the optics;
a wrench for removing nuts (the author of the video is the ZhZhZhoGGGovo channel).

Algorithm of actions

Before starting work, be sure to turn off the ignition - this will avoid a possible short circuit during repairs.

How to replace brake light bulbs:

First you need to open the trunk lid of the car.
Next, taking into account the design features of the car, you need to remove the plastic lining behind which the optics are located. As a rule, this stage does not cause difficulties; to dismantle the cladding, you need to disconnect four clips. This way you will be able to access the wing nut.
It is possible that access to the bottom nut will be blocked by another cover, in which case you will need to remove it. This cover is located in the same place as the lining.
After completing these steps, you will need to unscrew both nuts. One of them is located in a convenient place; unscrewing it is not a problem. As for the second nut, difficulties may arise with it, since its location is inconvenient, and therefore it will not be possible to unscrew it by hand. As a rule, a 22mm wrench is used to unscrew it; you only need to rip off the nut, after which you can use your hands. Be careful not to miss the nut, as you will have to disassemble the entire trunk to find it.
Once the nuts are unscrewed, you can remove the optics itself. Make sure that when dismantling both the upper and lower parts of the headlights are removed synchronously, otherwise the lamp may fall into the spacer. You may need the help of an assistant at this stage.
When the optics are removed, you will need to unscrew the three screws with a screwdriver. This way you can get directly to the light source. The old product is removed and a new one is installed in its place.
When the devices are replaced, the optics are assembled, all steps are performed in the reverse order. Now all you have to do is turn on the ignition and check the functionality of the installed light bulb by pressing the gas pedal.

Photo gallery “Do-It-Yourself Replacement”

In some cars, the replacement procedure is simpler. For example, in VAZ 2109 cars, you just need to remove the rear light trim, after which you will get access to the connector with the light source, which can be unscrewed and replaced with a new one. We considered the most difficult option.

Price issue

Lamp prices vary widely. On the market you can find products costing from 30 to 1000 rubles per piece.

We install the purchased lamp in the fog lamp

There are dozens of design options for a fog light, as well as ways to get to it. Different cars have different options, but in most cases you will have to approach the foglight from the rear. To replace a light bulb in some cars, it will be enough to remove the headlight from the slot and perform all the processes as simply and clearly as possible. But this is only an exception to the general rule. On most machines, everything is not so convenient. A popular method for replacing a fog light bulb looks like this:

we raise the car on a lift (this is best) or, if this is not possible, on a jack;
turn the wheel as much as possible so that it does not interfere with the work (on a jack the wheel can only be unscrewed);
remove the protection - often the fog lamp has a metal or plastic protection against dirt;
remove the sealing rubber bands, look for the latches that hold the light bulb in the fog lamp housing;
carefully and without sudden movements, we unclench and unscrew everything, take out the old light bulb and look at its characteristics;
if the purchased new lamp matches the old one, install it in the slot and press it with latches;
we put on the terminal, make the electrical connection as efficiently as possible, without a chance of falling off;
now an important step that many people forget about is to check the operation of the equipment by turning on the lighting;
If everything is fine, we put the protection back in place, put the wheel on, lower the car from the jack and rejoice at the update.

Remember that independently replacing a fog light or a light bulb in it during the warranty period is a reason to remove the car from warranty. Any processes during the warranty period must be performed at an authorized service station. If your car is already out of warranty, there is no point in paying several hundred rubles for a process that you can do yourself quite quickly. So save wisely, but only replace a lamp if you are confident in your skills.

Brake lights don't work - what's the danger?

This is a serious failure that can lead to driving safety problems because other motorists in traffic behind you will no longer be aware that your vehicle is braking. As a result, the distance between cars will be broken, which is unsafe.

You can find detailed installation instructions here. You may also be interested in an article about replacing generator brushes.

If an emergency occurs, the culprit will most likely be the owner of a car with a non-working brake light. As evidence, representatives of the road inspection use recordings from the video recorder, which is equipped with almost all modern cars.

What consequences can this lead to?

Brake lights, turn signals and side lights are very important, because they help ensure the safety of vehicles on congested highways. Thanks to them, other motorists can remotely determine the shape and size of the vehicle, as well as identify the maneuvers that you plan to carry out.

But fixing a situation with a faulty brake light is quite simple and most often it can be done without the help of specialists. The main thing is to determine the cause of the malfunction.

Problems with headlights of VAZ 2112 cars and their simple solution

The quality of lighting reduces the risk of getting into an accident at night and during bad weather

Therefore, it is important that the headlights in a VAZ 2112 car illuminate the road surface well. It is necessary to monitor the serviceability of the optics and carry out timely repairs

This article will help you figure out what optics are installed on the VAZ 2112, how to choose, and provides instructions for replacing lamps and adjusting headlights.

A modern car has a large number of lighting fixtures.

All of them are combined into a single lighting system that performs the following functions:

illuminates the road and side of the road;
signals the driver's intentions;
informs about the dimensions of the car;
illuminates the interior, engine compartment, luggage compartment, etc.

All devices are divided into external and internal lighting. The external ones include front headlights, turn signals, side lights, rear lights, license plate lights, fog lights on the VAZ 2112. The headlights on the VAZ 2112 are a block that contains several lighting devices: low and high beam lamps, side lights, DRL.

Turning and side lights are signaling lights. The former warn about the driver’s intentions to perform a particular maneuver, the latter inform about the vehicle’s dimensions. They are built into the front headlight and rear lights. A special feature of signaling devices is that they shine yellow and synchronously.

Requirements for installing daytime running lights on cars have appeared recently. They have an intense light, their function is to improve the visibility of the car when driving in the daytime.

In their absence, this function is performed by low beam or PTF. Fog lights on the VAZ 2112 are designed for driving during bad weather when visibility is poor. They are installed in pairs at the front.

The back may be missing.

The rear lights of the VAZ 2112, like the headlights, are block headlights. These include the exterior light, turn lights and side lights.

Tail lights VAZ 2111

The rear optics include a brake light, a luggage compartment light and a license plate light.

Interior lighting consists of: interior lights, engine compartment lights, door lights, trunk lights, glove compartment lights, and dashboard lights.

What kind of lamps are installed in the Priora headlamp?

The Priora's rear light has 4 lamps, which are responsible for turning on the turn signal, dimensions, reverse, brake light and PTF. They are almost the same, but have some differences.

The turn signal lamp is marked PY21W and is orange; when installing a regular white lamp, the turn signal will blink white.
The size and brake lamp has two spirals, which are responsible separately for braking and illumination.
The reverse lamps and PTF lamps are the same.

Tail light lamp marking table

Purpose of lamps	Marking	Peculiarities
Reverse	P21W	White
Turn signal	PY21W	Orange color
Brake light and dimensions	P21/5W	Two spirals for dimensions and a brake signal
Rear PTF	P21W	White

Where to begin?

There are cosmetics - colorless glass, multi-colored glass, even refractive glass. There is a technique - power and number of threads. Double-filament lamps are the second dimensions, and when you press the brake, the signal goes off because the second filament lights up, while the first one is constantly on. It's up to you to decide what is more important to you and what color it should be. The tools you will need are wrenches of different sizes, a Phillips screwdriver, double-sided tape and a screwdriver. The latter is the most difficult to deal with on the road, but it is an excellent tool for fixing any breakdown, so take a closer look at models with a battery or car charger - it will come in handy. You can only change the brake light bulb with the engine off, otherwise you may get an electric shock.

Typical faults

We propose to consider the most common malfunctions of the rear lights of Renault Logan 1.

Pay. Despite the fact that the car was supposed to be a budget car, the designers took the reliability of the headlight board extremely seriously. The lamps are powered not by thin tracks or even wires, but literally by busbars, which are impossible to burn even if you insert a crowbar instead of a fuse and short-circuit them.

To burn such tires, you have to try very hard.

The only trouble that can happen is oxidation or burning of the cartridge contacts. We remove the light bulb, inspect the contacts, and clean if necessary. There may be another problem with the cartridge - sagging of the lower contact, which is also a preloading spring. If a correctly installed lamp “dangles,” then this contact needs to be slightly bent outward with an awl or a screwdriver.

In the lamp socket, the marker/brake light of such spring contacts is 2

Connector A fairly common problem is burning of contacts. Typically, burning occurs when there is poor electrical contact between the block and its mating part on the circuit board of the lighting device. If the problem is noticed in time, then the contacts of the block can be put in order - cleaned, tightened, lubricated.

This board connector can still be restored

But if it burns out completely, you will have to replace the pad.

Such a block, of course, cannot be repaired.

Often, along with the block, the connector of the Renault Logan rear light board (part number 6001548137) also burns out. In this case, there is only one way out - buying a new board (there is a photo above), which costs around 1,500 rubles. Fuse.

More precisely, there are several fuses and each one is responsible for its own circuit. They are located in the mounting block, and the block itself can be found in the cabin to the left of the steering column.

Location of the mounting block Renault Logan 1

The fuses with the following numbers are responsible for the headlight located at the rear of the car:

F03 – brake lights, reverse indicator;
F04 – direction indicators;
F18 – side lights, left side;
F19 – side lights, starboard;
F20 – rear fog lamp.

Finding them is not difficult - just look at the picture below.

Brake light switch. This problem, of course, only affects the brake indicators, which automatically turn on when you press the brake pedal. Their operation is controlled by a limit switch located under the brake pedal lever.

Brake light limit switch location

This is, in fact, an ordinary button with two contacts, and ringing it will not be a problem - you just need to know how to use a multimeter.

Reverse signal switch. Here the principle is the same as for brake lights, only the limit switch is not located in the passenger compartment, but is screwed into the gearbox. We engage reverse gear, a special rod inside the gearbox presses the limit switch - the reverse light comes on.

The problem is diagnosed in the same way - we disconnect the power supply from the limit switch, check with a multimeter with the reverse gear turned off and on.

Important! If we are going to change the reverse limit switch, we place a container under the work area. As soon as we unscrew the limit switch, oil will flow from its seat

At the end of the work, be sure to check the oil level in the crankcase and, if necessary, add fresh oil (not the one that was drained during the replacement!).

Wiring. Basically, this is a violation of the insulation and a short circuit of the supply wire to the body. In this case, the fuse immediately burns out. If the circuit is “reliable,” then the new one will burn out immediately. If it is “floating”, it will burn out during the next trip (due to vibration). We carefully inspect the power harness of the faulty light fixture from the flashlight to the mounting block, look for frayed insulation, and fix it.

Causes of malfunction

Bulbs in the rear lights of a VAZ 2110
There may be several reasons why the lighting does not work. Each malfunction requires an individual approach and implies its own troubleshooting methods. Causes of the malfunction and methods for eliminating them (if some lamps of flashlights and headlights do not work):

burnt fuses - replace them (see VAZ 2110: how to replace fuses);
lamp filaments are burnt out - change the lamps;
contacts on relays or switches have oxidized - clean them;
the wires are damaged, their tips are oxidized or the connections are loose - replace the faulty wires, clean the tips;
The contact jumpers at the location of the lamp control relay have oxidized - clean them.

Rear fog lamp bulbs on a VAZ 2110
Sometimes the headlamp lens fogs up a lot. What are the reasons and what to do in this case:

leaky adhesion of the lens to the body - immerse the headlight unit in water, if liquid penetrates, replace the headlight;
moisture enters in the direction from the engine compartment during the process of washing the car - eliminate the liquid from the headlight unit.

How to change the brake light bulb on a Ford Focus 3

The Focus 3 attracts its customers with its unique design. Thanks to body aerodynamics, a low drag coefficient is achieved, which greatly affects fuel consumption.

And improved sound insulation of the engine compartment, wheel arches and underbody reduces noise in the cabin at high speeds.

Inside, the Focus 3 can be simple or have all sorts of useful electronic gizmos, depending on the configuration.

For example, replacing brake light bulbs.

Open the trunk. On the inside (right or left depending on which light bulb needs to be changed) opposite the lampshade, remove the protective cover.

Under the cover you will see two nuts in the form of plastic tubes.

Gently unscrew them with your fingers. If they do not give in, take the pliers without squeezing them (in the form of a fork), resting against the blades of this bolt along the axis and tear it off. Next, twist it by hand.

After unscrewing the bolts, pry the lampshade from the outside and pull it away from the wing (the direction is indicated by the mounting bolts). The narrow feather part of the lampshade closer to the door is held on a clamping clip. Be careful not to break this fastener.

When you remove the ceiling lamp, you will see the sockets with turn signal bulbs and a brake light with a parking light.

After changing the required light bulb, reassemble everything in the reverse order.

There is no need to tighten the bolts securing the rear lamp with pliers; there is a possibility of stripping the threads.

Have a nice trip!!!

What does this mean?

Accidents. But they are not the main problem. “Kisses” on the highway are a common occurrence; repairs should normally be provided by the insurance company; in a country with a more developed insurance industry, you would simply exchange business cards with your agents and go your separate ways. In Russia everything is a little more complicated. If you brake without turning on the rear brake light, the driver behind you sharply reduces the distance, and when you collide, from the point of view of the traffic police, you will be the culprit. These include fines and sometimes even the risk of losing your license. The operation of the brake light is easy to check - almost every car now has a recorder installed. It is enough to raise the records.

Replacing a brake light bulb is, in most cases, such a simple operation that it is not worth the risk of driving a damaged car.

Buy a high-quality fog light bulb

To buy a good light bulb, just contact the store with a professional consultant. Here they will tell you which manufacturers are the most reliable, which lamp models have sufficient brightness for your car model. The design of the fog lights also determines the type of light element required. Some good, reliable bulbs simply won't fit into your headlight because they're too long. There are also options for types of bulbs - you can buy halogen, LED or xenon bulbs for fog lights. The choice is influenced by the following factors:

if the replacement occurs in one headlight, you should pay attention to the type and brightness of the lamp in the second fog lamp; it is necessary to comply with the power, which is a limitation of the manufacturer of a particular headlight; It is also worth purchasing a lighting element of exactly the shape that is necessary for normal installation; it is necessary to make sure that the thermal activity of the lamp does not destroy the headlight and its surrounding elements; when purchasing a lamp for an original factory headlight, it is best to buy an official lighting element from the manufacturer; overpaying for the purchase of light elements usually pays off handsomely, the lamp will last longer, and the quality of its work will not disappoint you.

Everything suggests that it is better to buy expensive equipment that will work functionally and for a long time. Many believe that an excellent opportunity would be to change the factory settings and install a more functional LED lamp or xenon lighting element. This solution is not suitable for all fog lights. Therefore, before performing this task, it is best to consult with a specialist who can evaluate the design and requirements of your fog lights.
