Detailed Description

Standard Ignition SLS-118 is a brake light switch designed to meet the electrical and mechanical demands of service replacement work. The internal contact arrangement is engineered to maintain consistent switching action, while copper alloy conductors support efficient current transfer. This helps maintain proper brake lamp activation and signal response in vehicles where the switch is part of the cruise control-related brake circuit. For Jeep Cherokee, Jeep Comanche, Jeep Grand Wagoneer, Jeep Wagoneer, and Jeep Wrangler applications, the SLS-118 provides a focused replacement option for the original stoplight switch function.

This part cross-references Dorman - HELP 58112 for the same application.

What It Helps Fix

• Brake lights that do not illuminate when the pedal is pressed
• Intermittent stoplamp operation caused by worn switch contacts
• Brake signal issues affecting cruise control-equipped Jeep models
• Delayed or inconsistent brake pedal switch response
• Electrical resistance problems at the switch connection

Installation Notes and Tips

Verify connector style, terminal count, and vehicle application before installation. This switch uses a 4-blade male terminal layout and one connector location, so the harness and terminal orientation must match the original setup. Confirm the vehicle is one of the listed cruise control applications before ordering or replacing the part.
