FIELD ADJUSTMENT AND INSPECTION OF HEADLIGHT AIM

ADJUSTMENT AND INSPECTION OF HEADLAMP AIM MAY BE ACCOMPLISHED BY FOUR METHODS: VISUAL, OPTICAL, PHOTOELECTRIC, AND MECHANICAL. VISUAL AIM IS THE SIMPLEST BUT THE LEAST ACCURATE. THERE ARE PROBLEMS WITH AN OPTICAL AIMER ALSO. TWO PHOTOELECTRIC AIM SYSTEMS ARE AVAILABLE. THE FIELD PHOTOELECTRIC AIMER LACKS THE REQUIRED PRECISION AND ACCURACY FOR AIM ADJUSTMENT AND INSPECTION. THE "THIRD DERIVATIVE" PHOTOELECTRIC AIM SYSTEM IS ACCURATE AND PRECISE BUT VERY EXPENSIVE. HOWEVER, MECHANICALLY AIMABLE LAMPS CAN BE AIMED AND INSPECTED WITH MECHANICAL AIMERS, WHICH ARE LESS EXPENSIVE AND MORE ADAPTABLE TO FIELD OR SHOP AIM ADJUSTMENT OR INSPECTION. WHEN USED WITH MECHANICALLY AIMABLE LAMPS, MECHANICAL AIMERS ARE MORE ACCURATE THAN VISUAL, OPTICAL, OR PHOTOELECTRIC SYSTEMS AND SHOULD BE USED FOR AIM ADJUSTMENT AND INSPECTION IN THE FIELD AS WELL AS FOR SERVICE. /HSL/
