Brake light switch

Brake light switch

Brake light switch is a small device attached to the brake pedal mechanism. Despite its small size, the brake light switch plays an important role in a modern car.
Brake light switch is installed above the brake pedal. Many vehicle systems including Push-Button start, Antilock Brakes and Vehicle Stability Control cannot operate if a brake light switch is not working properly.
The brake light switch serves two major functions. First, it turns on the brake lights when a driver presses the brake pedal. Second, it sends the signal to the vehicle computer that brakes are applied. A car with a faulty brake light switch is UNSAFE to drive.
