Automatic Headlight Beam Control System
An Automatic Headlight Beam Control System (AHBCS) for a motor vehicle includes two phototransistors as a
normal light sensors, one has a field of view forward of the vehicle, while other has a field of view normal to the road surface
and it facilitates not only auto-switching of the headlight but also, beam modulation. This article aims at describing the work
accomplished for the development of AHBCS.
