ABSTRACT:
A mechanism for adjusting the vertical or horizontal aim of a vehicle headlamp includes a rod-like link supported by a slide to move linearly relative to a housing and having an outer end connected to the headlamp. The inner end portion of the link includes a helical thread form which meshes with a second helical thread form on a rotatable driver extending perpendicular to the link. When the driver is rotated, the thread forms coact to advance or retract the link and thereby adjust the headlamp. A plastic bushing snaps onto the driver and into the housing to support the driver for rotation in the housing.
