A headlight bulb in a G6 may fail for several reasons, such as moisture buildup, age, or front end damage to the vehicle. Replacing a damaged bulb should be a priority to ensure your safety when driving. The process of replacing a headlight in a Pontiac G6 can be a little trickier due to the snug-fitting headlamp assembly, but it is definitely within the car owner's ability.

  • Make sure your starter switch is off to prevent short circuiting.
  • Make sure to use only 12-volt bulbs.
  • It may be necessary to readjust the headlamps after replacing the bulb.
  • You may want to apply tape along the edge of the bumper and headlight assembly to avoid scratching the paint.
