Most vehicles manufactured in recent years use a modern lighting system. The electrical installation of a car is the system on which the lighting is based. Without the latter, a vehicle cannot be seen and cannot illuminate the road in difficult visibility conditions.
As time evolves, the lighting system also becomes more and more sophisticated. Therefore, it is important to understand the latest design to quickly solve a problem, especially when the tail-lights no longer work. It is essential to know that today almost all cars are equipped with organic LEDs or “OLED” as rear lighting (brake lights, rear turn signals, or reversing lights).
The main advantages of this type of lighting are a powerful and wide light range, as well as resistance to high temperatures of over 85 ° C. OLEDs also benefit from a long lifespan and robustness. However, in the event of a breakdown, this recent model requires specialist intervention. Modern lighting in most vehicles also has cosmetic enhancements, safety features, and also offers electrical benefits.
With all the features, there are some drawbacks you are also likely to encounter. Driving with rear lights that do not come on, especially brake lights, results in a hefty fine. As soon as you notice the slightest malfunction of one of the rear lights, do not hesitate to consult a professional garage. You can also buy replacements from auto parts shops like XENONS4U. BMW X3 F25 SUV is one car model that has experienced most of these drawbacks. The model has very attractive taillights that look great when functioning and may prove difficult to repair after getting damaged.
Types of Tail Lights in a Vehicle
The tail-lights of a car are specially designed to act as a signal to a driver who is behind your vehicle.
- The brake lights, usually red, indicate that the driver behind you to slow down. In certain vehicles, in addition to the two rear lights, the brake light located on top of the rear window is added. As soon as you press the brake pedal, the brake lights should come on automatically.
- The rear turn signals, conventionally orange in color, allow a user behind your car that you are going to make a right or left turn or overtake.
- The reversing lights emit a bright white light. As the name suggests, they only light up when you reverse or maneuver to signal the driver behind or near your car.
Common Causes of LED Rear Lights Problem in BMW X3 F25 SUV
BMW has used a LED taillight design made from low quality and poorly designed electronic components. This has brought about a lot of issues for owners who are forced to cope with poorly functioning products, which are costly to repair. You might be forced to spend a lot of money for an OEM replacement of the failed part.
Most owners of this particular BMW model have had issues with their tail lights, which tend to become dim with time. Some drivers have also complained that after failing to use their cars for an extended period, their LEDs would light up as usual then fail after using them for a short period. This error is a sign of a problem with the electronics. Most owners who have experienced such a challenge have taken their vehicles to dealerships. Those with their cars still covered by warranty have had the issue fixed at no costs at all. However, the problem keeps reoccurring after some time.
The other problem has to do with the rear turn signal. It is common to have one or both of the turn signals that do not work when you activate the control from the steering. In general, when these lights are activated, a “repeater” sound signal on the instrument panel is emitted simultaneously with the flashing of the light. If the fuse box is damaged, the taillights (turn signals) will not work with the front ones.
Aside from a fuse problem, the taillights can also experience lug failure caused by heavy play or oxidation. This can be solved by disconnecting and reconnecting them, or replacement if necessary. You may also be faced with a malfunction of the switch linked to the brake pedal (in the case of brake lights). A professional usually suggest changing this part to avoid prolonged failure. When the electrical circuit is faulty, no tail light comes on. Service or replacement of wires may be necessary after a multimeter or voltmeter diagnosis.
Brake Light Problems
You have a problem with the brake lights when you brake, and these lights do not come on. Burnt out bulbs are the most common when it comes to brake light failure. When a diagnosis does not reveal any faults in the electrical installation, this must constitute the first finding by elimination. In order to see in broad daylight that your brake lights are not working, you have to back your car against a wall or a window and press the brake pedal. If no red color is reflected on the surface, it means your lights are out. The opposite indicates well-functioning fires.
DIY Steps to Fix the Tail Light Problem in BMW X3 F25 SUV
Here are simple steps you can follow to fix the rear light problem in this BMW model.
- Remove the tail light unit by following the right procedure.
- Look for the Valeo b003809.2 Board. You can locate it quickly because it is in the plastic casing of the rear light. It is a weak point of the LED lighting system, and it requires upgrading.
- Disconnect and eject the old Valeo B003809.2 driver. Remove the white connector from the PCB board and LED lights before ejecting from the position.
- Install the B0038092 board meant for replacement. You should fix the new PCB driver before attaching the PCB board to the LED circuit.
- Fix the rear light back in place.
Always consult a professional if you want these problems fixed correctly.
