Aligning is goofy on aftermarket... the screw furthest to the outside finder is up/down and screw to the inside is left/right. But it is goofy because with my expierience, I go up and adjust and then do the left or right. If you go left or right to far then th sucker starts going up!
The way I have always adjusted HID's on the vehicles I have done....is by glare. Find a dark road at night and set out two reflectors on the road and adjust your glo. That has worked best for me. Damn if you put some tape on the garage door and get them suckers aligned, go drive it at night and them suckers are all kiddywampus!
When aligning my lights what exact screws are you talking about? I have no idea which ones??
