A vehicular lamp with an LED light source in which light from the LED light source is formed into parallel light fluxes by an optical member, and the parallel light fluxes are reflected by a reflector in the forward direction of the lamp. The bottom-face wall of the lamp body that houses the reflector has a translucent portion, and the LED light source and the optical member are disposed outside the translucent portion so that they are unrecognizable. The reflector is formed by a translucent member and is provided at a distance from the translucent portion of the lamp body and from the rear-face wall of the reflector, so that the parallel light fluxes from the optical member is subject to internal reflection.
