go to an auto parts store and get a "ford headlight adjuster" or whatever they call it, I have one somewhere, it's a plastic knob with a little female hex on one end. They are adjusted with little adjusters, if you look close enough you'll find them, two on each side. I wouldn't attempt this unless you have either the tool mentioned or a very small socket (it's in the area of 4mm), most other methods just screw up the adjusters...
