Detailed Description

The Standard Ignition SLS-487 brake light switch is built for vehicles that rely on a spring-actuated stoplight switch to signal brake pedal movement.

This part number, SLS-487, also cross-references Beck/Arnley 201-1976 for the same application.

What It Can Help Fix

• Brake lamps that do not illuminate when the pedal is pressed
• Stoplights that stay on after the pedal is released
• Intermittent brake light operation
• Brake pedal signal issues affecting vehicle warning systems
• Electrical switch failure at the pedal assembly

Installation Notes and Tips

Verify the connector shape, terminal count, and activation style before installation. This switch uses a push-in mount and does not include a wiring harness, so the existing vehicle connector must match the female rectangular interface and blade terminal layout. Confirm the vehicle-specific notes for 2006-2007 Audi A6 Quattro with black connector, 2002 Audi A4 with 4-pin configuration, and 2002 Audi S6 from chassis # 4B-2-129 477.

Quality Assurance

Standard Ignition supplies electrical replacement parts for OE-style service applications, and SLS-487 is built to match the listed fitment and connector requirements for the covered Audi and Volkswagen vehicles.
