Abstract

A headlamp aim adjuster is provided including a housing generally secured to a fixed portion of a vehicle and an aim pointer fixed to the housing. The headlamp aim adjuster further has a driven rod mounted by the housing and extendable therefrom to set a distance between the fixed portion of the vehicle and a lamp unit, a drive shaft rotatably mounted to the housing wherein rotation of the drive shaft determines the extension of the rod from the housing, and a position indicator being spring biased to a first position for adjustable movement relative to the housing. The position indicator has a zero ('0') marking so that upon establishing the desired aim position of the lamp unit by rotating the drive shaft, the position indicator is located with the zero ('0') marking in line with the aim pointer. The headlamp aim adjuster further includes a restrictor for retaining the position indicator in a second position to prevent movement of the position indicator zero ('0') marking from the aim pointer when the lamp unit is initially being adjusted.
