What are the causes of car brake light failure?

[VonEmma]

Car brake light failure can be caused by: 1. Open circuit in the wiring or grounding; 2. Malfunction of the brake light switch; 3. Burnt-out bulb. The car brake light provides direct indication of the vehicle's braking status to following vehicles during driving. If the brake light fails to illuminate, trailing vehicles cannot promptly determine the driving status of the preceding vehicle, which can easily lead to rear-end collisions. The brake light is installed at the rear of the vehicle with a red-colored main body to enhance light penetration, ensuring that following vehicles can easily detect braking actions even under low visibility conditions, thereby preventing rear-end collisions.
