herk01SS

Didn't know exactly where to put this thread. I have a problem with the driving lights on my 01 SS. Neither of them can be adjusted down far enough to hit the road, they are adjusted so far that the screw comes out and still aim up. I thought they were broken at first and bought another one just to find they were ok. Anybody run in to anything like this? It doesn't look as though there is an adjustment in the bracket, that I can figure out anyway. Anybody have any ideas?
Thanks
