Detailed Description

Standard Ignition SLS-154 is designed for Chevrolet and GMC brake light switch applications where consistent stoplamp activation is required. The switch construction uses high-grade materials and copper alloy conductors to support low-resistance electrical transfer, while the contact arrangement is built to limit arcing and extend service life. This makes it a practical replacement for GM truck and SUV brake pedal switch service on models such as Chevrolet C1500, K2500, and Blazer, as well as GMC C1500, K3500, and Yukon.

This part cross-references Standard Ignition SLS154T and Dorman 1S5183 for the same application.

What It Helps Fix

• Brake lamps that do not illuminate when the pedal is pressed
• Intermittent stoplight operation
• Delayed or inconsistent brake signal output
• Electrical contact wear inside the brake switch
• Replacement needs on aging Chevrolet and GMC brake pedal switch systems

Installation Notes and Tips

Verify connector style, terminal count, and vehicle application before installation. Confirm the brake pedal switch is seated and adjusted according to the vehicle service procedure so the stoplamps activate at the correct pedal position. Inspect the harness connector and terminals for corrosion or heat damage before connecting the new switch.
