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.|||i had a bronco ll of the same year just open the hood and reach for the bulb assembly it%26#039;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.|||http://autorepair.about.com/
