Abstract
A vehicular lamp having an improved luminous intensity of reflected light that has passed through a tinted topcoat layer. Light emitted from a light source bulb is reflected by a reflector to form an outward beam. The reflector is formed of an effective reflector portion contributing to formation of the outward beam and a non-effective reflector portion not contributing to formation of the outward beam. Only the non-effective reflector portion or only the non-effective reflector portion and an extension portion are coated with a tinted topcoat layer. The particle diameter of pigments dispersed in the tinted topcoat layer is limited to a certain range.
