go to your mercury dealer they know how to do it so you dont need to worry about itI need to change the headlight bulb on a 2002 mercury cougar, can someone please explain how to replace.?Check and make sure you are getting the right bulb at a parts store when you buy it. Your car probably uses a H9007 or a H9004 bulb. You have what is called %26quot;composite headlights.%26quot; That means the lense is one part and the bulb is replaceable from the back. You might be able to reach the bulb from the back of the housing. All you do is open the hood and look behind the back part that the lense is mounted to. There should be a pigtail that plugs into the back of the bulb. There is a plastic retaining ring that holds in the bulb. The way I take out the bulb is to turn the ring and remove the bulb, ring, and pigtail all at the same time. Then I pull the pigtail off of the bulb and discard it. Install the bulb in the hole in the back of the headlight assembly taking care not to touch the glass part of the bulb. Touching it will cause it to blow out within 2 weeks. If you touch it just wipe it off with a paper towel soaked in alcohol to remove the finger oils. After it is in the hole and seated, (the little tab that the pigtail locks onto should be on top,) put the plastic retaining ring on and turn it to lock it into place. Plug the pigtail back into the back of the bulb.I need to change the headlight bulb on a 2002 mercury cougar, can someone please explain how to replace.?pop the hood look behind the blowmn bulb. twist the base counter-clockwise and pull. the bulb should come out. pull the bulb straight out. then reverse the steps to replace.I need to change the headlight bulb on a 2002 mercury cougar, can someone please explain how to replace.?Instructions are found on page 52 of the owners manual....
