a first illumination portion provided in a cab capable of elevation in a vehicle and irradiating a first notification light toward a road surface behind the vehicle;
a second illumination portion provided on a vehicle body incapable of elevation in the vehicle and irradiating a second notification light toward the road surface; and
a control unit controlling a lighting state of the first illumination portion and the second illumination portion according to a travel state of the vehicle body and an elevation position of the cab,
wherein the control unit turns on or blinks the first illumination portion and turns off the second illumination portion when the travel state is backward travel and the elevation position is lower than a predetermined threshold value; turns off the first illumination portion and turns on or blinks the second illumination portion when the travel state is backward travel or travel stop and the elevation position is equal to or higher than the threshold value; and turns off the first illumination portion and the second illumination portion when the travel state is forward travel.
