輌用灯具。 It includes a lamp housing, a lens that covers the front surface of the lamp housing, a light source placed inside the lamp housing, and a reflector placed on the back of the light source, and the reflected light from the reflector near the light source is projected onto the outer circumferential side of the lens. The reflection angle of the reflector is set so that the lens is divided into a part near the light source and an outer peripheral part, and the part near the light source of the lens is configured with a prism that allows direct light from the light source to be emitted parallel to the optical axis. A vehicular lamp characterized in that the outer peripheral portion of the lens is constituted by a prism that refracts the light reflected from the reflector and emits the light parallel to the optical axis.
