Replacing the Brake Light Bulb

Once you have access to the back of the tail light assembly:

Tips for Bulb Replacement

  • Always handle new bulbs with clean hands or gloves to avoid leaving oils on the glass.
  • Consider replacing both brake light bulbs at the same time for even illumination.
  • If the new bulb doesn't work, check the fuse or have the electrical system inspected.

      While LED replacements are available, ensure they're compatible with your vehicle's electrical system to avoid issues.
