PROBLEM TO BE SOLVED: To prevent or suppress degradation of discernment of a driver occurring immediately after a luminous intensity in a vehicle width direction is varied depending on a vehicle speed.SOLUTION: Each of headlamps 2R and 2L that illuminate a space in front of a vehicle 1 includes three or more light sources which are different from one another in an irradiation range in a lateral direction. The plural light sources are classified into first area light sources R1 and R2 (L3 and L4), a second area light source R3 (L2), and a third area light source R4 (L1) by differentiating the irradiation ranges of the light sources in the lateral direction. A controller U independently controls the luminous intensities of the area light sources according to a vehicle speed. The controller U implements luminous intensity control that falls into light reduction control under which light is reduced but is not put off, light increase control under which light is increased, and intermediate control under which luminous intensity control is implemented so that a change in a luminous intensity is smaller than those under light reduction control and light increase control. |
