What is a Brake Light Malfunction?

[VanKhloe]

Brake light malfunction refers to the situation where one or both brake lights fail to illuminate when the brake pedal is pressed. If the brake light bulb is not burnt out, it indicates an abnormal vehicle fault code, which can be resolved by visiting a repair shop to clear the fault code. Generally, vehicles are equipped with at least two brake lights, one on each side. Some vehicles also have an additional high-mounted brake light on the rear windshield. The function of the brake lights is to illuminate when the driver presses the brake pedal, signaling drivers behind to maintain a safe distance. If a brake light malfunction is not addressed promptly, it fails to alert following drivers, significantly increasing the risk of rear-end collisions. Note: Car brake lights and brake discs have a limited lifespan and must be replaced when worn beyond a certain point. Under normal urban driving conditions, the lifespan of brake discs is approximately 50,000 kilometers, while brake pads last about 30,000 kilometers. However, actual lifespan depends on the driver's habits, and it is recommended to inspect them every 10,000 kilometers. In addition to brake pads, brake fluid should also be replaced regularly, ideally every 50,000 kilometers.
