Abstract

A courtesy logo lamp or a courtesy lamp is installed in a part on the interior side of a door of a vehicle. The courtesy logo lamp or the courtesy lamp includes a light source, a light guide and an outer lens. The light guide includes a light input surface that allows input of light from the light source, a light guide portion that guides light input from the light input surface, and a light output surface that allows output of the light guided by the light guide portion. The outer lens includes a transmission/diffusion portion. The transmission/diffusion portion allows input of the light output from the light output surface of the light guide, from a back surface, penetration of the light in the thickness direction and diffusion of the light, and radiation of the light from the front surface to the outside.
