Locate the bulb cover at the back of the assembly. Unclip and open the cover to expose bulbs.

Remove the electrical connector and pull out the bulb that you want to replace. The low beam bulb is held in place with a clip. Other bulbs are held by friction; use pliers to gently pull them out.

Put in the replacement bulb and reattach the connector. Do not touch the bulb glass with your bare hands -- oils from your fingers will remain on the glass and cause it to crack when it heats after turning the lights on.

Replace the bulb cover.
