Taillights are the light assembly mounted on the rear of your Audi. The tail light assembly activates when the front headlights are turned on and are usually inactive during the day. They are less bright than brake lights, but they allow other drivers to see you better than having no lights on at all, particularly in heavy rain, fog, or other weather conditions.
While the brake lights and tail lights are confused and used interchangeably, they are different. The taillight assembly is crucial to your safety on the road, as this light notifies other drivers of your presence. While the brake light alerts other drivers behind you of the change in your speed and helps them adjust theirs accordingly, the tail light notifies other drivers of where you are located on the road.
Sometimes, tail lights can develop faults that cause the light to not function. This can put you and other drivers in danger. Let’s take a closer look at tail lights issues and discuss a few things you can do to resolve the tail light issues with your Audi.
- Issues with the Fuse Box: A blown-out fuse or any other issues with the fuse box will affect the tail lights in your Audi. It is advisable to check in with a specialist who will help you change the blown-out fuse. While you may be tempted to do it yourself, the specialist can detect the source of the problem so it doesn’t recur.
- Blown out Bulbs: Tail light failures may also be a result of a blown-out tail bulb. The blowout of the bulb might have been accelerated due to a faulty fuse. A specialist is qualified to diagnose the problem and can advise you if it is from the broken filament in the bulb or a faulty fuse.
- Broken Control Switch: The control switch is in charge of lighting up the headlights, tail lights, and parking lights. A tail light failure may be attributed to a failed control switch. This is especially the case when all the other parts of the tail light are in proper condition. To have this checked and repaired, you will need an expert mechanic to pull it out from the dash and examine it. They will check this using a multimeter. Upon confirmation of its failure, they will make the necessary repairs.
- Socket Failure: Corrosion is the usual cause of socket failure. The sockets can go bad due to moisture. When this happens, the metal components become rusty and the pins can become broken or bent. Another cause for socket failure may be poor connections of the wires in the back of the socket.
- Bad Ambient Light Sensor: Your Audi may have light sensors on the dash. This sensor helps your car know when to turn on the lights, depending on how dark it is outside. If the sensor is bad, it will be difficult to tell whether it is dark or bright out. This sensor may not turn on the lights when necessary for your safety. Usually, this will affect all the lights of your Audi, not just your tail lights. An Audi specialist will be able to determine the cause and fix this so you can get back on the road safely.
