ABSTRACT:
The present invention envisions a headlamp calibration assembly for use with an adjustable headlamp assembly. The headlamp assembly includes a housing, a reflector adjustably retained in the housing and horizontal and vertical aiming devices. The housing has a viewing port formed therethrough for viewing inside of the housing for observing the movable headlamp component, for example the reflector. The calibration assembly includes an adjustably mounted lens positioned over the viewing port, horizontal position indicia on the reflector positioned for viewing through the lens and viewing port including a zero adjustment indicator represented by a selected one of the horizontal position indicia, and sight means on the lens in the form of indicia or the like for sighting and alignment with the horizontal position indicia to attain zero adjustment as discussed above. The sighting device on the lens includes two pairs of spaced apart parallel lines on either side of the lens to eliminate parallax when viewing the horizontal position indicia. Additionally, the sighting device can be formed on a magnifying prism formed in the lens so that smaller indicia may be used to thereby increase the precision of the horizontal adjustment. The horizontal position indicia may be positionable on or proximate to a vertical position indicating device such as a spirit level. The vertical position indicating device may be positioned for viewing through the lens and viewing port.
