How To Replace A Chevy Cobalt Headlight Bulb

The Chevrolet Cobalt is an efficient, compact car Chevy created to replace the Cavalier and Prizm. It comes in both a sedan and a coupe, and like all vehicles, at some point or another, you are going to need to replace a burned out headlight.

You can save yourself a little money by doing it yourself, and here are the easy instructions.


  • Wrench
  • Clean Rag
  • 9007 LL halogen headlight bulb

How To:

  1. Start by setting the parking brake and removing your keys from the ignition.
  2. Use the hood release latch that can be found under the dash on the driver’s side and open the hood.
  3. Go to the front of the vehicle, and slide the release latch that is under the hood towards the driver’s side to fully raise the hood.
  4. Find the headlight and take the bolts off the assembly. Put the bolts aside.
  5. Take the fasteners off the assembly molding and pull it back.
  6. Take the headlight assembly out by pulling it slightly at an angle.
  7. Disconnect the bulb base by lifting the plastic tab on the harness. Disconnect the wiring harness and take the black retainer off with a counterclockwise turn.
  8. Turn the bulb socket counterclockwise in order to disconnect it. Gently pull the bulb out of the socket.
  9. Replace the old bulb with your new one, and reverse the steps to reassemble the headlight. Use 89 inch-lb torque to retighten the bolts.

Clean the new headlight, turn the key to “ON” and make sure that you have reconnected everything and your bulb is working.

TIP: If you don't handle the new bulb with your bare hands, you shouldn't have to clean it. Just use a clean pair of gloves, or grab a sandwich bag and use it like a glove when handling the bulb. Not only does this save you a step, but it reduces the odds that some dirt or grime on the bulb's housing will shorten its' life.
