Abstract
A movable shade is moved by a shade driving device between a first shade position which is positioned on an optical axis at a rear focal point of a projection lens and a second shade position which is located further downward than the first shade position. Even in the event that there is provided only a single light source, low beam light distribution patterns and high beam light distribution patterns can selectively be formed. In addition, the light source is moved by a light source driving device between a first light source position which is positioned on the optical axis and a second light source position which is positioned further forward than the first light source position. Then, four types of light distribution patterns can be formed through combinations of the positions of the light source and the positions of the movable shade.
