Vehicle headlamp assembly with calibration restrictor

摘要

A vehicle headlamp assembly is provided, having an adjustment device for adjusting the position of a lamp unit and wherein in a preferred embodiment the adjustment device is combined with a rotatable recalibration arrangement that includes a position indicator: in the form of a disk member provided with teeth at its periphery and in which the teeth of the disk member are shielded by a wall so as to prevent accidental movement of the disk member when the latter is positioned to indicate the aimed position of the lamp unit in the horizontal plane. Additionally, there is a calibration restrictor that holds the position indicator in the zero ("0") position during initial adjustment of the lamp unit during vehicle assembly.
