I'm driving a 2014 prostar and the headlights are pretty much aimed at the ground. I can't find any adjustment screw on this thing at all. I tried turning the little nut that takes a 6mm socket but it did nothing... Not sure what it's for. The mechanics at me company don't know where it is either. I've adjusted headlights on Peterbilts, KWs, and freightliners with no problem. Does anyone know where the headlight adjustment screw is on the 2014 prostar?
