Standard Ignition Brake Light Switch P/N:SLS-388
Standard Motor Products
Your brake lights come on only when this switch tells them to. The Standard Ignition Stoplight Switch / Brake Light Switch SLS-166 is the pedal-operated switch that completes the brake-light circuit each time you press the brake. It fits many vehicles, among them the 1992-2002 Ford Crown Victoria, 1995-2002 Ford Grand Marquis and 1990-1991 Ford Country Squire. See the "Vehicles it fits" section for the full list and engine details.
Robust design and high-grade materials are intended to meet the demands of today's service professional. Signs the stoplight switch may need replacing include brake lights that stay on, brake lights that fail to light when the pedal is pressed, or lights that work only intermittently. Bulbs, fuses, and wiring can cause the same symptoms, so diagnose the circuit before replacing the switch.
