たことを特徴とする車輛用灯具。A light fixture in which a light source is arranged in a lamp chamber defined by a housing and a front lens, the front lens having a central part facing the light source and an outer peripheral part on both sides of the central part, and the front lens having outer peripheral parts on both sides of the light source corresponding to the outer peripheral part. A side lens is disposed so as to be inclined outward with respect to the optical axis, and the side lens is provided with a side lens that controls side light from a light source into substantially parallel light beams in a direction perpendicular to the side lens. An inner prism and an outer prism are formed in the housing, and the housing has a reflective surface part that allows the light that has passed through the side lenses to enter the outer periphery of the front lens, and a reflective surface part that makes the rear light from the light source enter the center part of the front lens. A vehicular lamp characterized in that it is provided with a reflective part that makes the light worse.
