Automotive Headlamp Aiming - Intentions and Results

This paper outlines some of the problems encountered on the state level in enforcing regulations regarding the accurate aiming of motor vehicle headlamps. State regulations vary throughout the United States, as does the enforcement of such regulations. The State of Virginia has taken a number of steps to ensure that the headlights on vehicles operating within the state are the best possible: training and retraining of inspectors; improved supervision of the inspection process; adaptation of the aiming tolerances allowed in SAE J599, Lighting Inspection Code; and a constant awareness that state officials must keep up to date with changes in the technology and engineering of lighting devices.
