Brake Light Switch - CI XBLS237

The brake light switch's primary function is to signal the vehicle's brake lights to illuminate when the brake pedal is depressed, warning following traffic.

Symptoms include brake lights not working at all, staying on constantly, or only working intermittently. A visual inspection for damage or testing the switch's electrical continuity can also indicate a fault.

The switch has dimensions of 75 mm in length, 75 mm in height, and 50 mm in width.

The CI XBLS237 is compatible with OEM part numbers 55701396, 71746722, 6239120, 6240187, 9185907, and 3774083E00000. It's essential to verify these numbers against your vehicle's specifications or consult a mechanic.

If you have experience with automotive electrical systems, you may be able to install it yourself. However, it is often recommended to have a qualified mechanic perform the installation to ensure it is done correctly and safely.

This describes the electrical connector attached to the switch, which has two pins arranged at an angle to ensure correct orientation and a secure connection to the vehicle's wiring harness.

Check the electrical connection to the switch. Ensure the switch is properly installed and the brake pedal is engaging the switch mechanism. Verify the vehicle's brake light bulbs are functional and check fuses related to the brake light circuit.

The switch may be stuck in the 'on' position, or there might be an issue with the return spring or linkage. Inspect the switch for physical obstructions or damage. If the switch itself is faulty, it will need replacement.

This could indicate a loose electrical connection, a worn internal mechanism within the switch, or corrosion. Clean the electrical connector contacts. If the issue persists, the switch likely needs replacement.
