Abstract:
Provided is a vehicle light system using an existing vehicle-internal lamp and a vehicle-external lamp, the vehicle-internal lamp and the vehicle-external lamp cooperating to provide directive lighting. The vehicle light system comprises: a light control unit that generates and outputs a control signal for controlling the turning on and off of both the vehicle-internal lamp and the vehicle-external lamp; a light source drive unit that drives the light source of any lamp of the vehicle lamp group on the basis of the control signal provided from the lighting control unit; an in-vehicle device installed in the vehicle and having a wireless communication function; a portable device that can be carried outside the vehicle by an occupant of the vehicle and that has a function of communicating wirelessly with the in-vehicle device; and an in-vehicle network connecting the in-vehicle device and the light control unit. The light control unit acquires position information for the portable device through the in-vehicle network, and generates and outputs a control signal whereby both the vehicle-internal lamp and the vehicle-external lamp cooperate to provide lighting when within a predetermined range. The commercial value of a vehicle light can thereby be increased.
