How do you replace the headlight bulb located on a 2001 Honda Civic EX?

Depending on the side it is on you may need to lift out the reservoir in the way. The reservoir is on the drivers side behind the rear of the headlight assymbly. It will easily slide up and out of the way. Just pull it up. Next remove the electrical connector. Next pull off the rubber flange/seal. Now you will see a metal clip. Look closely and you will see that on the bottom of the clip is a small screw that secures the clip in place. DO NOT REMOVE the screw. On the opposite side of the screw which will be the top side all you have to do is push in and away. This will dislodge the clip and the bulb will fall out. Put the new bulb back in and reverse the proceedure. Hope this helps.
