Also known as the Set Stop Lamp Switch or Brake Pedal Switch, this critical safety component activates the brake lights when the brake pedal is pressed, ensuring safe driving and compliance with traffic regulations.
What is a Brake Light Stop Lamp Switch?
The Brake Light Stop Lamp Switch is a safety-critical component mounted near the brake pedal. When the driver presses the brake pedal, the switch activates and sends an electrical signal to illuminate the brake lights at the rear of the vehicle.

Additionally, this switch signals the Engine Control Module (ECM) for functions like cruise control deactivation and gear shift interlock release.
