Your brake lights come on only when a switch signals that the pedal has been pressed. If the switch that does this job is failing, the Standard Ignition Brake Light Switch SLS-510 is the replacement cataloged for it. It fits many vehicles, among them the 2009-2021 Ford F-150, the 2009-2023 Ford Escape and the 2009-2023 Ford Explorer, along with other Ford, Lincoln, Mazda and Mercury models.
A brake light switch senses when the brake pedal is applied and switches the brake light circuit on, so the brake lights illuminate while you are braking and go out when the pedal is released. This signal lets drivers behind you know you are slowing down.
- Part type: brake light switch, manufacturer part number SLS-510 (also written SLS510).
- Quantity: the listed applications use one switch per vehicle.
- Engine: cataloged for all engines on the listed applications.
Signs a brake light switch may need replacing: brake lights that stay on after the pedal is released, brake lights that do not come on when the pedal is pressed, or lights that work only some of the time. A burned-out bulb, a blown fuse or a wiring fault can cause the same symptoms, so diagnose the circuit before you replace the switch.
See the Buyer's Guide tab for the full list of Ford, Lincoln, Mazda and Mercury applications.
