A position sensing detector or CCD camera (22G,22D) is located at the side to receive reflected radiation. After calibration to determine the lengths (D1,D2) of the incident rays the vehicle depression and roll are calculated and automatic compensation applied An Independent claim is also included for : A method for continuously regulating the orientation of vehicle headlights for varying depression and roll through the use of calibrated infra red or similar sources, adjacent detector and headlight positioning equipment",
