How to adjust projector headlights!

I recently purchased a set of Angel eye/Halo projector head lights and I am puzzled as to how to adjust the projector head lights. I can only see about 10 feet in front of me and I know thats not right. So can someone tell me how to fix this situation.

I guess it would help to know which lights you have but...

i have owned 2 different sets of projectors and they are a pain to adjust...

on the back of the headlamp there are adjustment screws around the lights...it's likely that they are on the bottom of the light making it that much more fun to adjust them. turning these screws adjusts the light. usually there are 3 screws sometimes 2.
