What is a Tail Light?
A tail light, also known as a rear lamp, is a crucial safety feature on vehicles. Its primary function is to provide a visual warning to other drivers, pedestrians, and cyclists of your vehicle’s presence, particularly when braking or slowing down. Tail lights are usually located at the rear of the vehicle and come in various shapes, sizes, and designs.
Why Does My Tail Light Go Out When I Brake?
There are several reasons why your tail light might go out when you brake. Here are some of the most common causes:
1. Faulty Brake Light Switch
The brake light switch is responsible for sending an electrical signal to the tail light when the brake pedal is pressed. If the switch is faulty, it may not send the signal, causing the tail light to go out. This is a common issue and can be easily replaced.
2. Worn-out or Damaged Brake Light Bulb
Over time, brake light bulbs can wear out or become damaged. If the bulb is not functioning properly, it may not illuminate when the brake pedal is pressed, causing the tail light to go out. Replacing the bulb is a simple and inexpensive solution.
3. Faulty Wiring or Electrical Connection
Wiring and electrical connections can be prone to damage or corrosion, which can cause the tail light to malfunction. If the wiring is damaged or corroded, it may not send the electrical signal to the tail light, causing it to go out.
4. Brake Light Module Failure
The brake light module is a complex electronic component that controls the brake lights. If it fails, it can cause the tail light to go out. This is a more serious issue and may require professional attention. (See Also: How to Undo Emergency Brake? Simple Steps)
