This is an easy fix with a relatively low frustration quotient. If only 1 headlight is burned out, resist the urge to replace both headlights at the same time. You don't want them to burn out simultaneously in the future.

Difficulty: Moderate
Instructions

Things You'll Need:

    Determine Which Lights Are Burned Out

  1. Step 1

    Turn on the lights and determine which headlight is burned out.

  2. Step 2

    Figure out what kind of headlight your car uses. Some cars have a replaceable halogen bulb inside the headlight. On other cars, you need to replace the entire headlight.

  3. Step 3

    Buy the headlight or bulb you need at an auto-parts store. The salespeople can help you find the right headlight or bulb for your car. The procedure differs depending on what type of headlight you're installing.

  4. Install a New Halogen Bulb

  5. Step 1

    Open the hood and find the wires that go into the back of the headlight.

  6. Step 2

    Twist the black plastic ring at the back of the headlight to release the bulb.

  7. Step 3

    Pull out the bulb and unplug it.

  8. Step 4

    Carefully take the new bulb out of the box without touching the glass part with your fingers (see Warning). Plug it in and place the bulb back into the headlight.

  9. Step 5

    Twist the plastic ring back on and test the new headlight.

  10. Replace an Entire Headlight

  11. Step 1

    Unscrew the tiny screws that secure the thin metal frame holding down the headlight. Do not turn the ones that have little springs behind them (see Warning). You may not need to take out all the screws to remove the headlight; sometimes you can leave the frame hanging by 1 screw.

  12. Step 2

    Put the screws in your pocket.

  13. Step 3

    Pull out the headlight and unplug it.

  14. Step 4

    Plug in the new headlight.

  15. Step 5

    Turn on the headlights to make sure the new light works.

  16. Step 6

    Put the metal frame back on and screw it down. A magnetized screwdriver will will make it easier to hold the screws in place.

Tips & Warnings
  • Do not touch the glass on a new halogen bulb. The oil from your fingers will cause the bulb to fail prematurely.
  • Don't turn the adjusting screws when replacing the headlight or you will have to readjust it. The adjusting screws have little springs behind them. The screws that hold the headlight in place are smaller and have no springs behind them.
