Abstract
A vehicle headlamp assembly provided with an adjustment device for adjusting the
position of a lamp unit and wherein 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.
