How do you change low beam headlight?

I've got a 2006 Trailblazer with the passenger side low beam burned out. I went and picked up a new lamp for it but there is no instructions in the owners manual showing how to do it. It doesn't seem like you can get at it from the back side and it looks like it could possibly be done by releasing clips at the top of the headlight casing and dropping it forward for access. But, I'm not sure so I thought I'd post here for ideas.
