There is an adjustment screw on the back side, right next to the dust cap.Can someone post a pic or say where the adjustment is for the headlight? Once I installed my HID's my passenger side is a good bit higher than the driver side. I noticed when I put the headlight assembly back in there was "wiggle" room, I basically bolted the (2) 10MM bolts at the top "centered" in the tabs. If you have looked at the tabs you will know what I'm talking about. I could push them in or out and tighten them down but figured center would be best, now just looking for what moves the headlight up and down adjustment wise, Kia Tech info just shows a picture of a screw driver and not where it goes, its just pointing at the head light lol.
