i just did the 9005 convo and i want to adjust them a bit lower, and wondering how do i go about doing it? i don't have any of the shop manuals or books.

 

Next to your headlight housing, there are two areas of adjustment. One is for horizontal and the other is for vertical. It's kinda hard to explain without a picture, but to adjust it, you'll need a screwdriver and a flashlight...

Do you have the owner's manual that came with the car? Inside there it shows you exactly how to adjust your lights.
