a. Service Headlight.
(1) Remove nut which secures light body to bracket, observing that conical washer bears against cup of bracket for secure light mounting. Disconnect wires from light body terminals.
(2) Before installing service headlight, connect wires to light body terminals, noting that black wire with red tracer connects with the larger terminal screw. Mount light on bracket. Position conical‐shaped washer and lock washer and install mounting stud nut. Do not tighten mounting nut.
b. Adjust Service Headlight. Adjustment should be made in darkened area or at night, tactical situation permitting. Vehicle must be standing on a level surface about 25 feet away from and headed toward a wall or screen upon which a horizontal line has been drawn at exactly the same height as service headlight center. Set handle bar toggle switch in “BRIGHT” position and check light beam for height and direction. The top of main beam of light should register on wall or screen even with, but not higher than, the horizontal line mentioned. Tilt light body in bracket up or down to correctly aim it in relation to the horizontal line, making sure that light body is not turned either to right or left. Securely tighten mounting stud nut.
