I used the needle nosed vice grips to adjust mine. Ford apparently had an intern design the distance on the adjustment screw to the frame....there is none. I haven't adjusted them since I put the leveling kit on, since 2009, and I got behind my wife the other night and she MADE me adjust them, they were entirely too bright. I would get flashed often, but never really did anything until last week. Actually, I can see alot better since I adjusted them down. Oh well, thanks for the thread.
