How to adjust headlights properly?
I just installed a set of harley headlights in my 06 F150. I notice now that the trucks left headlight shines a little lower than the right. And that said, I am not sure either is in the "optimal" position now since I did them both at the same time without comparing one to a factory one. So I know there is a way to adjust them against a wall from a certain distance and what not. I see there is a little square screw on each light which I assume adjusts the beam up and down? So my question is, which way do I turn it to go up and which way to go down? Also, is there an adjustment screw for left and right positioning? Does anyone know the distance I need to be away from a wall, and how high the center of the beams should be on said wall? Thanks for any advice!
By the way, my truck is a stock FX4, sitting on stock 20" wheels.
