How do you replace a headlight bulb on a 2003 Ford Explorer?

On the top of each headlight assembly, you will see two small semi-circular tabs. Pull these tabs upwards - you may have to use a wrench or screwdriver to put some force into it, as they tend to get stuck with road salt and grime. Once they move upwards, about 3/4 inch or so, the headlight assembly will release. You can then pull the headlight assembly forward and out of the truck. It will be attached only by the wires. Rotate the lightbulb assembly counter clockwise, and the bulb will come out. Replace the bulb, put it back into the headlight assembly, and rotate it clockwise to lock it in. Replace the headlight assembly, making sure the three screw/nuts are in the locking tabs correctly. While pushing the headlight assembly inwards, press the two locking tabs back down. This will lock the headlight assembly back into the truck, and realign the headlight, so that it does not have to be aimed again.
