The present invention combines control for lighting on/off a right side semiconductor-type light source 5R, control for lighting on/off a left side semiconductor-type light source 5L, and control for moving a movable shade 7 between a first position and a second position via control for driving/stopping the movement mechanism 70 with one another so as to radiate luminous intensity of a light distribution pattern HP1 for high beam having a first function, a light distribution pattern HP2 for high beam having a second function, and a light distribution pattern HP3 for high beam having a third function toward a forward direction of a vehicle 3. As a result, since the present invention includes a set of lamp unit, in comparison with the conventional vehicle headlamp system, the present invention requires a less number of components, and thus downsizing and cost reduction can be achieved accordingly.
