What is a Brake Light Switch?
The brake light switch is a vital component in your vehicle’s safety system, located on a bracket behind the brake pedal. This simple on/off switch activates the brake lights whenever the brake pedal is pressed. By completing an electrical circuit, it powers the brake lights or a relay controlling them. In addition to lighting up the brake lights, the switch can also play critical roles in other systems, including:
- Disengaging cruise control
- Allowing automatic transmissions to shift out of parkSet product image
- Activating engine start/stop functions
Depending on the design, some switches activate the circuit when pressed, while others work when released. If the switch malfunctions, it could result in brake lights staying on, flickering, or not illuminating at all.
Signs of Brake Light Switch Failure
Here are some common symptoms of a failing brake light switch and their potential impacts:
1. Brake Lights Won’t Illuminate
- Problem: Brake lights do not turn on when pressing the brake pedal.
- Cause: Likely a faulty brake light switch.
2. Brake Lights Stay On
- Problem: Brake lights remain illuminated even when the pedal is released.
- Cause: Switch could be stuck in the “on” position.
3. Intermittent or Flickering Brake Lights
- Problem: Brake lights work inconsistently.
- Cause: Corroded or loose contacts inside the switch.
4. Cruise Control Won’t Disengage
- Problem: Cruise control does not cancel when tapping the brakes.
- Cause: Faulty switch fails to send the signal, creating a potentially unsafe situation.
5. Car Won’t Shift Out of Park
- Problem: Automatic transmission won’t release from park.
- Cause: Transmission interlock solenoid isn’t activated due to a bad switch.
6. ABS or Traction Control Warning Lights
- Problem: Dashboard warning lights activate unexpectedly.
- Cause: Some systems rely on the brake light switch to monitor braking.
7. Engine Start/Stop Won’t Engage
- Problem: Engine doesn’t restart after lifting off the brake.
- Cause: The switch may need replacement or adjustment.
Troubleshooting & Fixing Your Brake Light Switch
Testing the Switch
To diagnose the issue:
- Locate the brake light switch on the back of the brake pedal assembly.
- Manually activate the switch by hand. If the brake lights don’t respond, the switch is likely the culprit.
Adjusting or Replacing the Switch
Sometimes, a simple adjustment of the mounting bracket can restore functionality. If not, replacing the switch is a straightforward DIY task that usually takes only a few minutes. However, if the switch integrates with systems like ABS, cruise control, or engine start/stop, a malfunction could also cause additional system failures.
