Standard Ignition Brake Light Switch P/N:SLS-342
Keep your stop lamps signaling the moment you hit the pedal with the Standard Ignition Brake Light Switch SLS-173. It installs as a direct-fit replacement for the 1991-1996 Chevrolet P30 and 1991-1997 GMC P3500, restoring the pedal-actuated switch that tells the brake lamp circuit when the pedal is applied.
A brake light switch is a small but essential safety component, and other faults can produce similar symptoms, so diagnose the cause before replacing. When the original switch is confirmed faulty, SLS-173 restores its function on the covered trucks.
