Toyota Crown/Prius/Reiz Brake Light Switch 84340-30110 Universal Stable Output

If your vehicle’s brake lights stay on after releasing the brake pedal, or the brake light responds slowly when pressing the pedal, or lights come on and off intermittently, this indicates aging or sticking brake light switch contacts and replacement is needed. When functioning properly, the switch accurately senses pedal position and provides stable signals to the body ECU and tail lights to keep brake lights on with pedal press and off when released, ensuring driving safety. Fits Toyota Crown, Prius, Verisa, and many other models; OEM 84340-30110; installation requires disconnecting the battery negative first to avoid short circuits; ensure switch latch and pedal bracket are fully locked, otherwise signals may misreport.
