Help can't find hex for headlight bulb replacement

I have a 2000 Yukon D and I have to replace the low beam bulb behind the battery but I can find the two screws everyone is talking about nor can i do it from the inside Help

There should be two allen head pins pointing straight up above the headlight assembly. Stick a socket over these and remove them. The headlight assy. should come right out.

Or two L shaped pins ( per headlight ) that you swing out of the clip that holds them and pull them both up and out. No tools needed. Pull out entire headlight housing then unscrew the bulb socket( half a turn ) that needs the new bulb.

yes the L shape pins swing out 90 deg to remove the whole assembly, the posts with the star shape to them are turned for adjustment. You will need to go get a socket set for these, I got mine at NAPA - not too expensive and hey, NEW TOOLS BABY! Anyways, Use care removing the assembly to not catch the grill and snap something off...
