Brake Light Switch Stop Lamp Switch

The brake light switch is an electrical component located near the brake pedal in a vehicle.

Here’s a detailed description:

• OE Number

25320-BR00A

• Compatible Applications

• Function and Purpose

Primary Role: The main function of the brake light switch is to activate the brake lights when the driver presses the brake pedal. This signals to other drivers that the vehicle is slowing down or coming to a stop.

Additional Roles: In many vehicles, the brake light switch also plays a role in the operation of other systems, such as:

Cruise Control: Disengages cruise control when the brake pedal is pressed.

Transmission Interlock: Prevents shifting out of park or neutral without pressing the brake pedal.

Anti-lock Braking System (ABS): May interact with the ABS system for proper functionality.

• Location

Typical Placement: The switch is usually mounted on the brake pedal assembly. It is positioned so that it is activated when the brake pedal is pressed and deactivated when the pedal is released.\

• Symptoms of Failure

Brake Lights Not Working: If the brake lights do not illuminate when the pedal is pressed, the switch might be faulty.

Brake Lights Stuck On: Conversely, if the brake lights remain on even when the pedal is not pressed, this could also indicate a problem with the switch.

Cruise Control Issues: Problems with the switch can affect the functionality of the cruise control system.

Difficulty Shifting Gears: Issues with the brake light switch might prevent you from shifting out of park or other gears.

• Replacement

Process: Replacing the brake light switch typically involves disconnecting the battery, removing the old switch (often by unscrewing or unfastening it), and installing a new one in the same location. Make sure to check the vehicle’s service manual for specific instructions related to your model.
