Standard Motor Products SLS289 Stoplight Switch Brake Light Switch

The Standard Motor Products SLS289 is a direct-fit replacement stoplight switch — also commonly referred to as a brake light switch — designed to restore proper brake light operation and maintain critical safety signaling to other drivers on the road.

Built to the same standards as the rest of Standard Motor Products' extensive SLS-series line, the SLS289 features robust construction engineered to handle the electrical and mechanical demands of daily driving. Copper alloy conductors ensure superior electrical conductivity with minimal resistive losses, while a specially designed spring and contact arrangement reduces arcing to extend service life.

Key Features:

• Direct OE replacement — engineered to match original fit, form, and function
• Brass or high-impact composite housing for durability and long service life
• Copper alloy conductors for superior electrical conductivity and low resistive losses
• Special-design spring and contact arrangement minimizes arcing
• 100% tested to verify mechanical and electrical switching performance
• Sold as a single unit

A faulty stoplight switch can cause more than just dark brake lights — on vehicles with push-button keyless ignition systems, a failed brake light switch can also prevent the engine from starting. The SLS289 is manufactured by Standard Motor Products, one of the automotive aftermarket's most trusted independent suppliers, with full quality control maintained throughout the manufacturing process.
