Looking for a way to change headlight bulbs?

I have a 1990 Ford Bronco II and i need a way to change the headlight bulbs to a %26quot;superwhite%26quot; or a %26quot;cool blue%26quot; color, but the problem is that the headlight is an entire assembly, not just a lens, that i can replace the bulb behind it. Just need help with changing it to a different bulb type.Looking for a way to change headlight bulbs?i had a bronco ll of the same year just open the hood and reach for the bulb assembly it's on the Radiator support off to the side twist clock wise and pull it should come out put new bulb in and put back in the hole.Looking for a way to change headlight bulbs?http://autorepair.about.com/
