Abstract
A headlight testing system includes a target screen upon which an image of headlight illumination is projected. Reference indicia for intensity and positioning are also placed upon the screen. A video camera captures an electrical image of the screen, which is digitized to allow for analysis thereof. A second video camera is directed at the vehicle headlights, its generated image similarly being digitized. The digitized data are processed, reference being made to the reference indicia, to determine positioning and intensity of the headlights. An overhead monitor, viewable from the vehicle may be utilized to provide information to an operator positioned within the vehicle under test, the operator communicating with the system by a wireless link communications.
