I think i get you, the light bulb will be adjusted (i.e. Brighter rather than higher) but the projector still emits the light to the same place?
I also have the auto levelling projectors, and they still work. Just when i come up behind cars i can see one light brighter than the other, and when you look at the front of the car one bulb hits its bright point (when crouching if that makes sense) before the other.
They are levelled fine just literally need to move the other bulb up a tad.
So what does the light beam do when turning clockwise/ anti-clockwise as its a screw? i would of thought one way up one way down? Jus didnt know whether it did left/right up/down etc and didnt want to go buggering round with it lol
