Signal the brake lights the instant you press the pedal with the Standard Ignition Brake Light Switch SLS645. It installs as a direct-fit replacement for the listed application — the 2020-2024 Nissan Sentra [All] — restoring the pedal-actuated switching your vehicle relies on.
A brake light switch mounts at the brake pedal and opens or closes an electrical circuit as the pedal moves, telling the brake lamps to illuminate when you slow or stop. Depending on the vehicle's wiring, this switch position can also be referenced by related systems such as cruise-control disengagement and the brake-shift interlock, so a clean, consistent signal keeps those functions behaving as intended.
- Pedal-actuated switching: reacts to brake-pedal movement to control the brake-light circuit.
- Direct-fit replacement: a direct-fit service switch for the listed Nissan Sentra application.
- Replacement service part: supplied as a single switch (quantity 1 per application).
Signs this switch may need replacing include brake lights that stay dark when you press the pedal, lamps that stay lit after you release it, or a cruise control that won't set. If a failed brake light switch is the cause, this replaces it. Diagnose the circuit before installing to confirm the switch is at fault.
Manufacturer part number SLS645.
