Detailed Description

The Standard Ignition SLS-166 brake light switch is engineered for vehicles that rely on a precise stoplight signal at the pedal assembly. Standard Ignition uses brass or high-impact composite housings as specified, along with copper alloy conductors and a contact arrangement designed to limit arcing and support consistent switching action. This makes the SLS-166 a practical replacement for brake light circuit service on applications such as Ford Crown Victoria, Lincoln Town Car, and Mercury Grand Marquis.

For fitment-based searches, this part is commonly selected for brake light switch replacement on 1992-2002 Ford Crown Victoria, 1995-2002 Ford Grand Marquis, 1990-2002 Mercury Grand Marquis, 1990-1998 Lincoln Town Car, and 2000-2003 Lincoln Town Car. Standard Ignition SLS-166 also cross-references Anchor 8695 for the same application.

What It Helps Fix

• Brake lamps that do not illuminate when the pedal is pressed
• Brake lights that stay on after pedal release
• Intermittent stoplamp operation
• Crank or shift-interlock concerns tied to brake pedal switch input
• Electrical switching issues caused by worn internal contacts

Installation Notes and Tips

Verify connector style, terminal count, and vehicle fitment before installation.
