Okay,
My latest project so-to-speak on my Yukon Denali was headlight and park lamp housing replacement. Easy peasy to install.. but im not necessarily in great understanding about adjustment on the headlamps.. just need clarification.
I know the procedure to adjust them properly (25ft out, angled up to match as close as possible to the mark on the lens..info that is widely available). I also know that all GMT800 series trucks have two adjusting screws (one for up/down, one for in/out)
Stock Denali headlights (projector housings) seem to only have one adjustment for up/down.. am i correct or am i missing something. Even the old crusty OEM ones i took out only had one adjusting screw coming off the back of the housing. I do have them correctly (well..as close as possible) adjusted in the up/down axis. Cant find the in/out adjustment screw.. They seem to be aimed well though. Am i correct in thinking that the in/out adjustment is fixed due to the fact they are projector housings?
