Standard Ignition SLS-181 Brake Light Switch

Brake Light Switch for Cruise Control Applications

The Standard Ignition SLS-181 brake light switch is built for vehicles that need reliable stoplamp signal control, including 1990-1993 Chevrolet G10, G20, and G30 models with cruise control and 1990-1993 GMC G1500, G2500, and G3500 models with cruise control. It uses a 2-connector, blade-terminal design with a female connector and male terminals for direct electrical interface.

• Brake light switch for stoplamp circuit operation
• Blue and creme housing with plastic finish
• 2 connector design with female connector gender
• Male blade terminals, 2 + 2 terminal layout
• Built with copper alloy conductors for low-resistance electrical flow
• Spring and contact design helps reduce arcing during switching
• 100% tested for mechanical and electrical switching performance

Built for Reliable Stoplamp Switching

Standard Ignition SLS-181 is engineered as a brake light switch replacement for cruise-control-equipped Chevrolet G10, G20, and G30 vans and GMC G1500, G2500, and G3500 vans from 1990-1993. The switch uses brass or high-impact composite housing materials as specified by application, along with copper alloy conductors to support consistent electrical conductivity and durable operation in the stoplight circuit. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Issues This Part Can Address

• Brake lamps that do not illuminate when the pedal is pressed
• Intermittent stoplight operation
• Electrical switching problems in the brake pedal circuit
• Cruise-control-related brake switch signal faults
• Delayed or inconsistent brake light response
