Check the Brake Light Switch: Ensure that the brake light switch is properly installed and adjusted. Sometimes a misaligned or damaged brake light switch can cause the brake lights to stay on even after the brake pedal is released.

Inspect the Wiring: Look for any loose, damaged, or corroded wires in the brake light circuit. Ensure that the wiring connections are secure and free from damage.

Test the Brake Light Circuit: Use a multimeter to test the continuity and voltage in the brake light circuit to identify any faults.

Check the Brake Pedal Assembly: In some cases, issues with the brake pedal assembly, such as a worn or broken return spring, can cause the brake lights to remain on. Inspect the brake pedal assembly and replace any faulty components.

Consult a Professional: If you're unable to identify or fix the issue yourself, consider seeking assistance from a qualified mechanic or an auto electrician who specializes in electrical diagnostics and repairs. They will have the necessary knowledge and expertise to accurately diagnose and resolve the problem.
