What Causes the Central Brake Light to Malfunction?
2 Answers
Central brake light malfunction causes: 1. Brake light fuse damage; 2. Brake light switch damage. The brake light is usually installed at the rear of the vehicle, with a red-colored main body, making it easier for vehicles behind to notice when the front vehicle brakes, thereby preventing rear-end collisions. Central brake light malfunction solutions: 1. Locate the fuse box, find the brake light fuse according to the instructions, and check if the fuse is blown. If it is, replace it with a fuse of the same specification and model; 2. After locating the brake light switch, unplug the switch connector and use a wire to directly connect it. If the brake light turns on, it indicates the brake light switch is faulty and needs to be replaced with a new one.
I once experienced a central brake light failure while driving in the rain when a friend pointed out it wasn't working. Upon inspection, I found the bulb had burned out. The light is located above the rear window where dust accumulation or water ingress can corrode the bulb socket. It could also be caused by a blown fuse in the vehicle's fuse box corresponding to the brake light. Loose wiring connections leading to poor contact are also common, especially when vehicle vibrations cause plugs to come loose. Regular maintenance should include checking light conditions periodically. Bulbs typically last about two years before needing replacement - driving with non-functional lights is extremely dangerous as it increases rear-end collision risks. Any issues should be repaired immediately.
