Introduction

Eventually, all light bulbs burn out, and this applies to exterior lights on your vehicle, too. Changing a faulty brake light is something anyone can learn to do. A replacement bulb costs about $10, and replacing it on your own will save about $20 in labor and the time it takes to travel to the shop and wait for the work to be done.

Project step-by-step (4)

Step 1

Identify the Faulty Light

There are usually several lightbulbs underneath each tail light lens, and one of these bulbs is the brake light.

  • Have someone sit in the vehicle, pressing and releasing the brake pedal several times while you stand behind the vehicle and check brake light operation.
  • Identify which bulb under the taillight lens cover is the burned out brake light. There may be several bulbs under each lens, but only one is the brake lightbulb. Identifying where the brake lightbulb sits in under the lens may help you later when you’re searching for the correct replacement bulb.

Step 2

Find and Remove the Brake Lightbulb

Most modern vehicles allow access to all tail light bulbs from inside the trunk.

  • Open the trunk and look directly behind the tail light lens with the malfunctioning bulb. You’ll see the wires and a plastic base where each tail light bulb is located.
  • Use your head lamp or flashlight to determine which bulb in the housing is the brake light.
  • Turn the brake light holder counterclockwise to release it, then pull the bulb holder and bulb into the trunk.
  • Remove the bulb from the holder.
