ABSTRACT:
A lamp includes a projection lens, a reflector, and a prismatic lens. The prismatic lens receives direct light, which has been transmitted from the light source outwardly with respect to a widthwise direction of a vehicle, and refracts the received light toward the optical axis. The prismatic lens is separated outwardly from the optical axis in the widthwise direction of a vehicle and is provided between the projection lens and the reflector. The prismatic lens can provide an additional light distribution pattern formed outside, in the widthwise orientation, of a basic light distribution pattern formed from light passed though the projection lens.
