Abstract
A light unit 1 for a vehicle has a driving-environment detecting device 2 for detecting information (the shape of the road, the position of the vehicle, whether or not oncoming and preceding vehicle exist, the traffic volume density and ambient luminous intensity) indicating a driving environment provided by a path through which a vehicle is driven. A mode determining device 3 determines a driving mode which is included in driving modes classified in accordance with combinations of information detected by the driving-environment detecting device 2 and which is dynamically changed when the driving environment is changed during driving of the vehicle. In accordance with an instruction signal supplied from the mode determining device 3 to an illumination control device 4 and corresponding to the driving mode, illumination which is performed by the light unit 5 is controlled.
