Standard Ignition Brake Light Switch P/N:SLS-491
Restore reliable brake-light signaling with the Standard Ignition Brake Light Switch (Stoplight Switch), MPN SLS-179. Mounted at the brake pedal, this switch opens and closes the stoplight circuit as the pedal is pressed and released, telling the brake lamps to illuminate. It installs as a direct-fit replacement across a wide range of GM cars and vans, including the 1997-1999 Buick Century, 1992-1995 Buick LeSabre, 1995-1999 Chevrolet Camaro, 2000-2006 Chevrolet Impala, 1996-2005 Chevrolet Monte Carlo, 1993-1998 Pontiac Firebird and 1999-2005 Pontiac Montana — see the "Vehicles it fits" section for the full list of 47 applications.
Signs the original may need replacing include brake lights that stay off, stay on, or flicker when the pedal moves. If a failed stoplight switch is the cause, this replaces it. Robust design and high-grade materials meet the demands of today's service professional.
