headlamp removal on 2001 Silverado

I need to replace a low beam bulb on my 2500HD truck and my owners manual is not with the truck at the moment to see if it shows how to change the bulb.
Can someone tell me how to remove the lamp so I can get at the bulb harness to change the bulb.
Thanks for your replys

Once the hood is open if you look right above the headlight, there are some pins that slide in from the top that lock your headlight in place. They have a bent top that snaps into a holder, once you pull those the headlight will just pull out and you can remove the harness from the back of the fixture (don't try to pull straight out, they have to twist then pull out). There are some long bolts located right by the pull pins, don't try to unscrew those cause they are your adjusters. I put a set of Sylvania Silverstars in my truck and I like the brightness a lot better than the stocks. My truck is a 2002 HD so hopefully these directions help you out.

Thanks for the info. I changed the bulbs over to silverstar and like them so far.
