Abstract
A light output apparatus for vehicle according to an embodiment includes a transmission member disposed on an outer-surface side of a vehicle, the transmission member being adapted to let visible light pass therethrough, and to receive ultraviolet light and emit light by itself. The apparatus scans a visible light laser and an ultraviolet light laser, and projects the visible light laser and the ultraviolet light laser onto the transmission member. The apparatus performs control, based on vehicle information about the vehicle, to show first information by projecting the ultraviolet light laser onto the transmission member and thereby making the transmission member emit light, and to project the visible light laser onto the transmission member and thereby project second information onto a surface which the visible light laser reaches after passing through the transmission member.
