Remove the bumper cover, then take out the upper headlight housing bolt to detach the upper part of the headlight housing. Next, remove the three lower headlight mounting bolts to detach the lower part of the headlight housing. Pull out the headlight housing far enough to disconnect the electrical connectors, and then remove the headlight housing. To disconnect the electrical connector from a High Intensity Discharge (HID) bulb, rotate it 1/4-turn counterclockwise and pull it off. Installation is the reverse of removal.
