How do you replace the headlight bulb located on a 1992 Ford F-150?

I own a 1990 f-150, so it should be the same. Pop the hood and on the back of the headlight assembly is a seal, you can see the wires coming from it. Unscrew the seal and the light is right on there, just pull the light apart from the seal and your good to go, when putting the new light in, try not to touch the glass part of the bulb, because it somehow takes away from the life of the light. I know i didnt explain it that good maybe you can work with this
