Abstract

Each of a pair of lower reflection areas, which are located on both left and right sides of an optical axis in a lower end portion of a reflective surface of a reflector, respectively, is formed so as to converge light from a light source at a position located forward of a rear side focal point of a projection lens in a horizontal direction, and on the same lateral side as that of each of the lower reflection areas with respect to the optical axis. Thus, the pair of light ray bundles are emitted from the projection lens, whereby a pair of additional light distribution patterns are formed on both sides of a lateral direction central portion in an upper area of a high-beam distribution pattern, respectively. The upper area of the high-beam distribution pattern is thus made bright widely in a lateral direction.
