Standard Motor Products SLS304 Brake Light Switch Stoplight Switch

The Standard Motor Products SLS304 is a direct-fit replacement stoplight switch (also known as a brake light switch) engineered to restore proper brake light operation and braking system communication in your vehicle. Designed to OEM specifications, this switch activates your vehicle's brake lights when the pedal is depressed, signaling following drivers and enabling critical safety systems.

The stoplight switch plays a broader role than just illuminating brake lights. On vehicles equipped with keyless or push-button ignition systems, a functioning brake light switch is required to allow the engine to start — the system must confirm the brake pedal is depressed before the starter will engage. A faulty switch can result in a no-start condition in addition to inoperative brake lights.
