Detailed Description

Standard Ignition SLS-399 is a brake light switch engineered for vehicles that need reliable stoplamp activation when the pedal is pressed. The switch construction uses high-grade materials and a robust housing design to handle daily driving and repair-shop demands. Its copper alloy conductors support efficient current flow, while the contact arrangement is designed to limit arcing and maintain consistent switching performance over time. This part number is a practical choice for Chevrolet Chevy, Chevrolet Chevy Pickup, Chevrolet Chevy Monza, and 2004 Pontiac GTO applications listed in the fitment data.

This part cross-references 1S8743 and SL949 for the same application. Standard Ignition SLS-399 is a direct-fit brake light switch solution for drivers and technicians servicing stoplamp circuit faults on Chevrolet and Pontiac platforms.

Common Issues It Can Help Solve

• Brake lamps that do not illuminate when the pedal is pressed
• Intermittent stoplight operation caused by worn switch contacts
• Brake light staying on after pedal release
• Electrical switching problems at the pedal-mounted stoplight circuit
• Replacement needs for a failed brake pedal switch on Chevrolet Chevy or Pontiac GTO models

Installation Notes and Tips

Verify connector style, terminal layout, and vehicle application before installation. This SLS-399 uses a female connector with 2 male blade terminals, so matching the existing harness connection is important. For 2004 Pontiac GTO applications, confirm the vehicle is not equipped with cruise control, as noted in the fitment data. After installation, test brake lamp operation and pedal switch response before returning the vehicle to service.
