this thread is moving in waves - no posts and then everyone start to type at the same time, so i have to go back several times to get the whole picture of what is being said...
the light assemblies have a sensor that indicates position of the pivoting projector in relation to the stationary housing, the AHL is being programmed to recognize that location as "zero" at the end of the assembly line (i guess when the car is being calibrated for the wholesale delivery to a dealer) and not entire physical range of the headlight is being used for the entire motion of the projector...

so, yes, the system knows where the starting point is - that brings us to GT1 tool... GT1 supposedly is capable of testing each projector individually... I don't think Chris has a GT1 laying aroung his garage...
