ABSTRACT:
An improved vehicle headlight aiming apparatus is provided. The vehicle headlight aiming apparatus includes a reflective surface, a light intensity sensing device, and a light intensity comparator. The reflective surface is provided for receiving a light beam and reflecting a reflected lightbeam therefrom. The light intensity sensing device measures the pattern and intensity of the reflected lightbeam. The comparator compares the pattern and intensity of the reflected lightbeam to a known standard in order to provide headlight adjustment information. The comparator includes a plurality of externally-accessible plug-in memory modules for storing different headlight aiming standards. These plug-in memory modules are coupled to the comparator by way of a plurality of sockets mounted on the exterior of the comparator. A plug-in extension model having a serial communication port is also provided for coupling the comparator to external devices such as a printer or other computer equipment.
