Help keep your brake lights switching on the moment the pedal goes down with the Standard Ignition Brake Light Switch / Stoplight Switch SLS-255, which is listed under both names. It fits many vehicles, among them the 2004-2008 Ford F-150, 2008-2009 Ford F-250 and 2002-2006 Ford Expedition, as a direct-fit replacement for the listed applications. See the "Vehicles it fits" section for the full list and engine details.
This stoplight switch senses when the brake pedal is applied and completes the circuit that lights the brake lamps, signaling drivers behind you that you are slowing down. Signs it may need replacing include brake lights that stay on, fail to light, or work only intermittently. Diagnose the cause first, as bulbs, fuses and wiring can produce the same symptoms.
- Controlled production: Standard Ignition, a global manufacturer of original equipment ignition products, maintains full quality control across manufacturing, from individual components to the finished switch.
- Copper alloy conductors: deliver superior electrical conductivity with low resistive losses.
- Arc-reducing contacts: a special-design spring and contact arrangement is intended to reduce arcing for extended service life.
- 100% tested: each switch is checked to verify both mechanical and electrical switching performance.
Its robust design and high-grade materials are chosen to meet the demanding needs of today's professional technicians.

Frequently Asked Questions
Is this the right Expedition switch for the brake lights on my 2002-2006 Ford Expedition?
Yes, SLS-255 is a direct-fit brake light switch for the 2002-2006 Ford Expedition. The "Vehicles it fits" section lists every other application.
What does a brake light switch do?
It senses when the brake pedal is applied and switches the brake lights on. It then switches them off again when the pedal is released.
What are the signs a stoplight switch may need replacing?
Brake lights that stay on, don't light, or work only intermittently can mean the switch has failed. Check the bulbs, fuses and wiring first, since they can cause the same symptoms.
How is the SLS-255 built to handle repeated switching?
It uses copper alloy conductors for low resistive losses. A special-design spring and contact arrangement is intended to reduce arcing for extended service life.
Is the SLS-255 tested?
Yes. Standard Ignition 100% tests its parts to verify both mechanical and electrical switching performance.
