Abstract
Each horizontal adjuster mechanism used in connection with low beam headlamps must be either non-readjustable after the initial adjustment or equipped with a non-recalibratable vehicle headlamp aiming device (VHAD) which is set to zero when the vehicle leaves the factory. Vehicle manufacturers must either aim the lamps and provide a non-recalibratable VHAD which is properly zeroed or aim the lamps and provide a mechanism to prevent future readjustment. A headlamp adjuster may be rendered non-readjustable after the headlamp has been aimed by snapping down a snap-socket, placing a covering cap over the drive shaft, closing a one-way lid on a drive shaft cover, or by otherwise preventing rotation of the drive shaft.
