Abstract
A vehicle headlight and control system for a bus or large vehicle includes a headlight fixture with a center or low beam light source and side illumination light source operated independently. The side illumination light source may be activated when the vehicle is turning, as detected by the vehicle speed and steering shaft turn angle, to provide supplemental illumination. Both right and left side illumination sources may be provided, and may comprise LED light elements. The system may also include an audible sound generator to alert pedestrians when the vehicle is turning.
