Tail lights and headlights for the VAZ 2109 - selection, replacement, repair

Installation of rear lights of VAZ 2108, 2109, 21099 cars

Structurally, each rear light is a plastic housing with a plastic transparent lens, on which the areas of lamp luminescence are highlighted in different colors. The left and right lights are not interchangeable.

A plastic board is inserted inside the case. The board has a tape with printed conductive tracks and a common terminal for the connecting block of the wiring harness. Lamp holders are also installed on the board at the track output points.

Each rear light of VAZ 2108, 2109, 21099 cars has the following lamps:

— turn signal lamp A12-21-3

— side light lamp A12-5

— fog lamp A12-21-3

— reverse light lamp A12-21-3

— brake light lamp A12-21-3

The reflector does not have lamps. The board has a curved section with a mirror coating for the fog light lamp (reflector).

The wiring harness (plus) comes to the rear lights from the fuse mounting block: block Ш9 (Х9) on the left side of the car (driver's side) to the left rear light. From the left rear light there is a branch to the right one. The negative is the black wire in the blocks, connected to the screw securing the rear lights.

Tail lights of VAZ 2109 do not light up - repair and modification

The functioning of the rear lights of any car is necessary for road safety reasons. These devices at the rear of the car perform a lighting and information function (warn road users about the movement of the car).

On VAZ 21099 and other models, the lights turn on automatically when changing gears and moving the car backwards.

Structurally, the lights at the rear of the car combine the following components of the lighting system:

• reversing lighting;
• side lighting;
• brake lights;
• turn signals;
• emergency alarm.

The structure of the lighting devices is as follows:

• body made primarily of plastic (in some cases glass);
• lamp holder;
• latch for holding wires;
• diffuser of light rays for uniform illumination of the road surface. It is glued to the back of the product body, so if it breaks, it needs to be replaced along with the body.

The device of the rear light on VAZ 2109-2108 and 21099

The following types of rear lights can be installed at the rear of a VAZ 2108 or 2109:

• incandescent lamps. Inexpensive, but they break down relatively quickly and are not bright enough. Such lamps burn with a yellow light, which is not very visible in unfavorable weather conditions;
• halogen light bulbs . They are considered more modern and durable, since air is pumped out of their flask and inert gas is pumped in. There are models with H1 and H3 sockets on sale;
• LEDs . They burn with a cool white light and last several times longer than incandescent lamps. They are sold in strips and today often replace obsolete incandescent lamps.

Engine compartment modifications

In addition to replacing the power unit after it has exhausted its life, there are many components in the engine compartment whose wiring also needs to be replaced:

Numerous sensors in the engine compartment require special monitoring:

A useful addition to the functionality of the car is the acquisition of a modern anti-theft system.

Installing a modern alarm system is a special topic, since its work affects several main components and systems of a VAZ family car:

Advice: often manufacturers of alarm systems accompany the installation process with video and photo materials for each specific model of a particular family of cars. Before starting installation, you should read them carefully.

General alterations

Installing additional fog lights is a general modification because:

Causes and actions in case of breakdown

Among the reasons for the breakdown of the rear parts of the lighting system on a VAZ 21099, 2108 or 2109, the most common are:

• Bulb burnout. It happens due to wear or power surges and is almost the most popular reason for replacing rear headlights.
• Oxidation of contacts. Occurs due to poor quality of terminal contact, electrolyte leakage, or cracks in the battery case.
• Fuse failure. This cause of failure is due to voltage surges.
• The reverse sensor is broken or its wiring is broken.
• Burnt out contacts on the headlight film.
• Lack of ground on the board.

The most common and easiest fault to solve is a lamp burnout. The product must be replaced with a new one by turning off the light sources, opening the trunk and disconnecting the column of wires.

To do this, you will most likely have to remove the trunk trim of the VAZ 2108 or 21099, which is located behind the lamp. After this, squeezing the latches (they are located on the sides), you need to take out the panel and unscrew the lamp, after pressing on it. To install a new rear lamp, reverse the process.

Replacing lamps in the rear lights of a VAZ 2109
To clean the contacts from the white coating that accompanies oxidation, you need to clean them. To do this, remove the headlight unit. The ground must be returned to its place, and the nearby wiring must be tested for correct operation. Broken fuses on VAZ 2109 and 21099 are not difficult to find - their diagram is usually presented on the block cover.

If you are faced with the problem of constant lighting of the reversing lights, this may be caused by problems with the wiring or the cessation of operation of a special sensor located on the box.

When the car headlight switch stops working, you can get to it through the engine compartment or from underneath the car.

You can diagnose the failure of this component of the lighting system as follows:

• start the VAZ 21099 and shift it into reverse gear;
• close the contacts. The rear lights should light up at this time;
• Use a multimeter to check if the contacts are closed when you turn on the rear headlight switch, having first removed the switch;
• make sure that the contacts are soldered securely, assemble the switch and check its operation again. If a normal short circuit is observed, replace it.

Last resort - complete dismantling

The instrument panel of the VAZ 2109 is not so complicated that you cannot figure it out on your own. But in the absence of experience, it is better to entrust the repair to specialists, or to enlist the support of a partner who understands this matter.

Replacement process

The rear lights are attached to the body of a VAZ 21099, 2108 or 2109 car using 4 nuts. To dismantle the lighting system you will need:

• head at 8;
• extension.

The operating algorithm is as follows:

• To access the nuts, remove the 21099 luggage rack at the appropriate location (if the rack is installed).
• Disconnect the power plug that is attached to the board.
• Unscrew the 4 nuts using a wrench.
• When removing the last nut, hold the taillight outside to prevent it from falling and breaking.
• After removing all 4 nuts, remove the light.

When installing a new headlight on the rear of model 21099, do not forget to connect the wiring to ground, which is attached to one of the studs.

What can be changed in the electrical circuit

Let's figure out what exactly car owners undergo alterations.

Moreover, we will indicate only those alterations that are not prohibited by the manufacturer and current regulations:

For reference: the visual differences between the standard panel and the “high” one are that the radio compartment is moved to the level of the dashboard. Accordingly, the wiring on the VAZ 2109 under the instrument panel must be replaced.

Interior modifications

Many owners come to mind with the desire to improve the lighting in the car interior.

Let us remind you that inside a passenger vehicle there are several places equipped with lighting sources:

If you, as the owner, like a high panel in the cabin, then you cannot do without replacing the standard wiring. Because the:

Remaking the rear lights on a VAZ 2108/2109

In this story, the author decided to share how you can remake the standard rear lights on the VAZ 2108 and, accordingly, on the Nine. After such a modification, the lights begin to work in a fundamentally new way. Standard lighting lamps are replaced here by LED strip, which works much more reliably than lamps, and is also more durable. Such tuning is done quite simply and quickly; anyone who has once held a soldering iron in their hands can handle it.

Materials and tools for manufacturing: – black matte paint; – epoxy resin; – covers for lights (black); - LED Strip Light; – drill with drills; – diodes; – black silicone sealant; – soldering iron with solder, wires, scissors and other small items.

The process of tuning the lights: Step one. Installing LEDs and painting lights

First, you need to glue the LED strip to the outer part of the lantern. To do this, you first need to mark the flashlight and determine how the diodes will be located on it. Next, the LED strip must be fixed with epoxy resin. Otherwise, the tape will lag behind, since the diodes get quite hot during operation.

After this, you need to cut out squares from paper and stick them on each LED; this is necessary for protection so that the diode is not painted. Well, after that the flashlight is painted matte black directly on top of the LEDs. After the paint has dried, the papers can be removed and the diodes will be exposed.

Step two. Installing headlight covers

To hide the LEDs, covers are installed on top of the flashlight, which the author first purchases in the store. A pair of these lanterns cost 400 rubles; black lanterns were chosen. Thanks to this, the original lights are practically invisible even during the day, due to the fact that they are painted black. The pads are attached using black silicone sealant, this ensures good tightness and fixation.

Step three. Connecting diodes

To connect LED strips, you need to make holes for the wires in your original flashlight. Next, the wires are simply soldered to the contacts to which standard light bulbs are connected. The brake light and marker must be connected via diodes; diodes from rectifier bridges are suitable for this, since they are powerful enough for these purposes. Regular diodes can burn out. When you press the brake, not only the brake lights come on, but also the rear lights. And accordingly, you need to remember to connect the right and left turns.

That's all, at this point the tuning can be considered complete. You can see what happened in the video.

Causes of failure of the rear parts of the lighting system and driver actions

You can find out what the breakdown may be and how to solve the problem below. We will talk about modified nines.

Possible malfunctions of brake lights and their elimination

1. Due to a voltage drop, a short circuit may occur and the paws will burn out.
2. If it's time to strip the wires because the contacts have oxidized and the terminals do not conduct current well enough.
3. Often, in the event of a voltage drop, it may be necessary to remove and replace fuses.
4. If the reverse sensor contacts are broken or damaged.

Removing the brake light switch sensor

In case of the problems listed above, the easiest way, of course, is to install a new lamp. This happens without any difficulty: you just need to turn off the lights, open the trunk and remove the wiring block. After this, holding the fixing elements that are installed on the sides, remove the panel and unscrew the lamp. In its place, install a new light device and assemble the assembly in the reverse order. If we talk about stops, both lamps and one of them may not work, that is, only in one headlamp.

If such a problem occurs, it is necessary to immediately diagnose:

1. Check the fuse and, if necessary, replace it with a new one. Fixing a breakdown is not enough, because, as in the case of human diseases, a burnout may be a fault in the system that needs to be corrected. If this is not done, you can change the device until the end of the life of the VAZ 21099. One of the reasons may be a short circuit.
2. If the wiring in the signal lamp sockets has oxidized, the lamp needs to be twisted a little in the socket to scrape off the damaged layer. To make the work done more effective, you can clean the contacts with sandpaper.
3. If the lamps in the stops burn out, you need to replace it with a new one and check whether the system will work. And if the contacts are bad, they need to be cleaned both on the board and on the wire block.
4. If the tracks in the headlight circuit board are burnt out, then you can remove the board and visually diagnose its integrity. If there are burnt tracks, they can be modified by replacing the wiring.
5. The sensor is faulty or the electrical circuit is broken. First, you need to remove the red and white wires from the sensor and connect them with a piece of wire. If the brake lights come on, then the sensor needs to be replaced; if not, you need to check the electrical circuit. It needs to be checked for broken contacts.

Main reasons

Almost all problems related to automotive electrical systems can be solved in approximately the same way. You need to look for a potential or probable cause of malfunctions in the problematic object itself, or understand the system responsible for supplying power.

The situation is exactly the same with devices called brake lights. If they stop working, then you should look for the reason in one of the following points:

• There were problems with the fuse. It has oxidized or completely failed;
• There are faults in the lamps themselves or in one lamp, depending on how many stops are not working;
• The reason lies in the mechanism responsible for turning on the warning signal when the brake is applied;
• In the socket where the stop light is installed, the contacts have oxidized;
• More serious problems appeared related to damage to the wiring.

Based on the stated reasons why the feet may stop working, we can draw a completely objective conclusion. A truly serious malfunction concerns only wear or damage to the electrical wiring. Solving such a problem with your own hands is not always correct.

When the rear brake lights (left and right) or the additional central brake light repeater fail, do not rush to look for an auto electrician and offer him money to fix the problem.

There is a high probability that you will be able to do everything on your own. You will only need a standard set of tools for a motorist, as well as an understanding of how the lighting equipment in general works in your vehicle. Start with the most likely and fairly simple to solve possible malfunctions. Only if it turns out that the problem is bad or damaged electrical wiring, then it makes sense to visit a good car service center. It is better to entrust such tasks to experienced craftsmen. The main components for restoring the operation of brake lights on your own, you will need a spare working lamp, a control unit or a multimeter, as well as suitable tools.

It would be a good idea to study the owner's manual and understand how to get to the stops on your car.

Fuse

The first place to start is by searching for the mounting block in which the fuse responsible for the brake light is located.

Moreover, each machine has its own electrical circuit and specific location of fuses.

These can vary significantly depending on the vehicle, such as:

• VAZ 2110;
• VAZ 2107;
• Toyota Rav 4;
• Ford Fusion;
• VAZ 2114;
• VAZ 2115;
• Ford Focus;
• Chevrolet Lacetti;
• Lada Granta;
• Hyundai Accent;
• Renault Logan;
• Hyundai Solaris, etc.

A blown fuse quite often causes the failure of a number of equipment, including lighting devices. Check fuses visually and using a multimeter.

But there is a simple and effective way to check that takes a minimum of time. To do this, start the engine and hold down the horn button. This is not suitable for all car models, but on many vehicles the same fuse is often responsible for the sound signal and brake lights.

If this is not the case, we continue our search further.

Brake lamps and their sockets

Next, you should switch to the brake lights themselves. In most cars, to gain access to the feet, the luggage compartment is opened, the rear light bulb is removed, after which you can get to the feet themselves.

But the dismantling process may differ on different brands and models. Here, start from your car specifically; if necessary, look for hints in the operating manual. There are examples of cars where you can get to the brake light without removing the rear optics at all. You still have one main task ahead of you. It consists of gaining physical access to the faulty device, the lamp and the socket in which it is located. Not everyone can try to determine the problem by eye. Here it is better to take a different route.

The optimal solution would be to use new, similar lamps instead of potentially faulty ones. Therefore, you will have to buy a light bulb in advance and screw it in. If you can't find a lamp of a similar size, use a marker or turn signal repeater. Make sure these conditional controls work first.

When everything worked after installing the new lamps, you found the reason. You can confidently buy new matching stop lamps, replace old ones and reassemble the unit in reverse order.

It is extremely important to take into account one feature. Some modern cars have such a principle of operation of brake lights, in which when one car brake light fails for one reason or another, the second one automatically stops functioning. That is, sometimes checking one lamp does not give a result, since in fact the chances are 50/50 of replacing the burnt lamp, and not the one that simply turned off in tandem.

If replacing the light bulbs did not give anything, check the sockets themselves. It happens that they oxidize, this breaks contact, and the device does not turn on, although power is supplied to it. Also make sure that the socket is connected to the vehicle wiring. If necessary, the contacts are disconnected, cleaned with fine-grained sandpaper, and then returned to their place. Even during this procedure, it is recommended to apply a special lubricant to the contacts after cleaning.

One more thing. When checking the sockets, it is also worth taking new light bulbs. It happens that due to oxidation of the cartridge, the lighting device itself fails. That is, in fact, 2 malfunctions occur simultaneously.

Problems with the switch

The brake light on a car lights up the moment the driver presses the brake pedal with his foot while sitting behind the wheel. When pressed in this way, the force is transferred to a special mechanism. It is popularly called a frog. It is also a limit switch and it is also a classic brake light switch.

There are 3 main reasons why a frog or limit switch may not work:

• contacts have oxidized;
• carbon deposits appeared;
• corrosion has formed.

Despite the slightly different processes, the essence of the problem is the same. It can be eliminated by stripping the frog, or by replacing the stop switch.

If none of the options are suitable, there is a high probability that the problem lies in damage to the vehicle's electrical wiring. Here it’s up to you to decide whether to try to resolve the issue on your own, or seek help from qualified specialists.

Considering the complexity of the electrical circuits of modern cars, a better solution would be to visit a trusted auto electrician. But the final choice is yours.

Removing and replacing rear lights

1. It is best to make the replacement before wiring problems begin.
2. To work you need to remove the lights. On the VAZ 21099 it is hidden by a plastic decorative trim in the trunk.
3. Now unscrew the fixing screws on the trim and remove them.
4. Disconnect the block with wires and carefully remove it, being careful not to damage the board, because it sits tightly in place.
5. Now, using a 10mm wrench, unscrew the 4 nuts securing the headlight housing. Remove the part from the machine. Now you can install the new part and calmly begin the replacement.
6. The collection is done in reverse order (the author of the video is Automaniac1994).
