Abstract: A vehicle illumination system includes a road surface drawing lamp configured to draw, as a drawing on a road surface, predetermined information by emitting light toward a target comprising a ground, a wall or the like around a vehicle, an illuminance sensor capable of measuring an illuminance around the vehicle, and a lamp control unit configured to control the road surface drawing lamp. The lamp control unit is configured to control the road surface drawing lamp so that an illuminance of the drawing on the road surface is to be higher than the illuminance measured by the illuminance sensor.
