I had noticed on my foglights that there is a adjustment screw accessable from under the light itself. The hole for the screw is just in front of the two mounting screws. The hole is just big enough for a screwdriver to fit. Try turning it one way or the other to see what it does. It should raise or lower it the angle of the light. I was playing around with this a little bit when I had taken the fogs off of my old 'Tour and was putting them on my brothers 'Tour. Hope I am not too late on the info.
