Keep your brake lamps switching cleanly with the Standard Ignition Brake Light Switch SLS-171. This stoplight switch drops in as a direct-fit replacement for a range of 1980s–1990s applications, including the 1981-1982 and 1987-1988 Porsche 924, 1983-1991 Porsche 944, 1987 Chrysler Conquest and Town & Country, 1987-1988 Chrysler New Yorker, 1987-1991 and 1993-1995 Porsche 928, 1988 Dodge Dynasty, 1991-1994 Mercury Capri, and 1992-1995 Porsche 968 (all engines).

Signs the switch may need replacing include brake lights that fail to light, stay on, or flicker; diagnose the cause first, and if a failed brake light switch is at fault, this replaces it. The wiring harness, mounting hardware, and mounting bracket are not included. Country of origin: Spain.
