- Check All Brake Lights: Look at each brake light (left, right, and center) to see which one is not working.
Step 2: Access the Brake Light Bulb
- Open the Trunk or Tailgate: Depending on your vehicle, you may need to open the trunk or tailgate to access the brake light assembly.

Step 4: Inspect the Bulb and Socket
- Check the Bulb: Look for a broken filament or dark spots inside the bulb. If it’s burned out, it needs to be replaced.
- Inspect the Socket: Look for corrosion or damage. Clean the socket with electrical contact cleaner if needed.
Step 5: Install the New Bulb
