COMPATIBILITY OF HEADLAMP AIM AND INSPECTION

The requirements and disadvantages of the three headlamp aiming methods now employed, visual aiming on a 25 foot screen, mechanical aimers, and headlamp testing machines, 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 and future considerations are summarized.
