したことを特徴とする自動車用灯A light-concentrating inner lens formed with a linear Fresnel prism orthogonal to the longitudinal direction of this front lens is placed inside an elongated front lens formed with a diffusion prism such as a fisheye cut, and a light source is placed at the focal point of this inner lens. In the installed automobile lamp, an auxiliary Lenner lens having a semi-cylindrical shape and having a straight Fresnel prism with circumferentially cut grooves formed on its circumferential surface is placed between the inner lens and the light source so that its central axis is aligned with the center of the light source. An automotive light characterized in that the straight Fresnel prism is arranged parallel to the longitudinal direction of the front lens.
