Abstract: A vehicle lamp aiming device is disclosed having an adjustment shaft with a first marking, and a mounting nut with a second marking. One of the other of the markings is formed on a clip firmly, but still adjustably mounted to either the shaft or nut as the case may be. Initial proper alignment of the adjustment shaft amy be made with respect to the mounting nut. The vehicle lamp is then in proper alignment. The adjustable marking clip is then moved to set the lamp calibration. A replacement lamp may then be brought into proper alignment by threading the adjustment shaft to align the alignment marks. By using a firm clip, subsequent, inadvertent resetting of the clip may be avoided.
