Replacing a burned out bulb in your car headlamps or tail lights is not much harder than changing a bulb in a light fixture in your home. If you have a maintenance manual for your car, look in it for instructions pertaining to your particular vehicle. Follow these general steps to save money by changing your own bulbs.

Difficulty: Moderately Easy
Instructions

Things You'll Need:

  • Screwdrivers
  • Clean cloth or gloves
  • New light bulbs of the correct type
  • Goggles
  1. Step 1

    Gather a couple of basic tools. Usually all you will need is a Phillips head screwdriver, but some take the star-shaped drivers. Some have tabbed latches that can be turned by hand. Grab a soft cotton cloth or clean gloves for handling the bulbs.

  2. Step 2

    Raise the hood to access the car's headlights after ensuring the engine and light switch are turned off. Support the hood properly to avoid injury.

  3. Step 3

    Find where the wiring harness enters the headlight that is burned out. Usually, you just need to grasp the connector on the rear of the assembly and turn it about a quarter-turn counter-clockwise, pull straight back, then it will pop out. Release the clip that retains the bulb in the holder and wiggle the bulb loose.

  4. Step 4

    Wipe any dust and dirt away from the connector and the headlamp assembly, or use compressed air to blow it out.

  5. Step 5

    Replace with a new bulb and reinstall by reversing the procedure.

  6. Step 6

    Look at the tail light assembly for screws holding it to the car body. If there are none visible from the outside, open the trunk and look for a protective covering in the area where the tail lights protrude into the trunk cavity on the car. Sometimes it's just a piece of carpet; other times you'll need a screwdriver to remove a small piece.

  7. Step 7

    Remove the burned out bulb in much the same manner as the headlamp. Normally, they have a holder that has a tab-lock that rotates. Follow the same removal and installation procedures as in Steps 3 through 5.

Tips & Warnings
  • Use the soft cotton cloth or clean cloth gloves to handle bulbs. Oils from your bare fingers can cause the bulb to get hot and malfunction prematurely.
  • Don't try to force the new bulb into the holder. They normally have a tab and notch that only allows them to be inserted the right way.
  • Ensure your car's hood or trunk is securely propped up while you are working to avoid injury.
  • Wear eye protection when using compressed air to blow away dust.
