A first shade 32 is properly moved to vertically shift the position of a cutoff line, and furthermore, a lighting unit 20 is properly tilted in a vertical direction to displace a whole light distribution pattern in the vertical direction. Consequently, a light irradiation is carried out with a light distribution pattern at an irradiation angle corresponding to a vehicle traveling situation. In that case, a second shade 34 is properly moved to form a dark portion in a central part on the lower end of the light distribution pattern in a predetermined size if necessary. Consequently, the amount of a light irradiation on a short-distance region can be controlled finely, and a road surface on this side can be prevented from becoming too bright in a high-speed travel and a light reflected by the road surface which causes a glare can be prevented from being generated in a rain travel.
