Headlight removal on 2007 Yukon

Can someone post procedures (hopefully with pix) on the removal of the headlights? I changed my signal bulb and could only take out the 2 screws on top and the headlights still would not come off. I wonder if there is another screw somewhere. I checked the manual and can't find it there either.

I'm looking to get me some HID's pretty soon.

HID install

If you find out how to get the headlight out, that'd be great if you can share the info. I have heard you need to take the front bumper off, but I dunno. :crazy:

If you wanna do HIDs, you do not need to take out the headlight assemblies. Here's how I installed mine.
