Detailed Description

This brake light switch is designed for vehicles that use a screw-in pedal switch arrangement and a single rectangular connector. It is listed for applications including 1993-2002 Nissan Altima, 1998-2004 Nissan Frontier, 1987-2002 Nissan Pathfinder, 1990-2004 Subaru Legacy, 1999-2004 Subaru Forester, and 1991-2003 Isuzu Rodeo, along with many other Nissan, Subaru, INFINITI, Isuzu, Mercury, Geo, and Chevrolet models. The SLS-143 also cross-references Standard Ignition SLS-143 and Anchor 8640 for the same application.

Use this part when the brake lamp switch needs replacement on vehicles such as Nissan Pickup, Nissan Sentra, and Subaru Impreza. For fitment-specific service, verify cruise control notes where listed, since several applications are not compatible with vehicles equipped with cruise control.

What It Helps Fix

• Brake lights that do not illuminate when the pedal is pressed
• Brake lamps that stay on after the pedal is released
• Intermittent brake light operation from a worn switch
• Faults caused by damaged switch terminals or connector wear
• Pedal-switch electrical issues on older Nissan, Subaru, and Isuzu vehicles

Installation Notes and Tips

Install the switch in the original screw-in location and confirm the connector matches the vehicle harness before final assembly. Check pedal adjustment and switch plunger position during installation so the brake lamps activate and release correctly. Review the fitment notes carefully for cruise control exclusions on certain Nissan, Subaru, Isuzu, and Honda Passport applications.

Quality Assurance

Standard Ignition supplies this brake light switch as a service replacement part for listed applications. Confirm year, make, model, and cruise control equipment before ordering to ensure proper fitment.
