Abstract
A cooperative adaptive lighting system for motor vehicles in which a vehicle transmits its geographic coordinates and receives similar coordinates from other vehicles, pedestrians, and stationary warning devices. Using the coordinates, the vehicle computes distances, and relative position more specifically, to those entities. When the distances become sufficiently small, indicating that the entities fall within headlight range, the vehicle alters its headlight beams to either (1) throw more light on an entity, (2) reduce light reaching the entity as appropriate, or (3) change a lighting pattern as appropriate.
