GM-GMC: adjust headlight, gmc sierra, star shape

Question
How do you adjust the headlight on a 1996 gmc sierra 1500

Answer
In 1996 there were two light styles they were still using sealed beam and composite.  Both had an inverted torx or e-torx adjusting post to angle the lamp up and down or side to side.  The head of the adjusting post looks like a star shape and is usually located on the top side near near upper rad support.  They are not a very common socket, you may need to locate one or borrow one.
Hope this helps
