I looked in my information and they do not show me a picture of the adjusting screws to raise and lower or move left or right the beam pattern. It should be obvious. The instructions do say move the adjusting "gear" so I presume it it a knob of some description on the lamp unit itself. If you cannot find it go to an autoparts store or garage I am sure someone will quickly be able to point out its location to you.
