Compatibility of Headlamp Aim and Inspection

The paper discusses current efforts to increase the compatibility of methods of aiming and inspecting presently used two-beam headlamp systems. The three aiming methods now employed are named, and the requirements and disadvantages of each are presented. Charts indicate the accuracy of each method, and the probability of acceptance of a unit that is aimed mechanically and inspected by another method is determined. Recent work in the field is summarized, and future goals and considerations are noted.
