Abstract:
A vehicle lamp with a projection lens; a light source; a shade, which forms a cutoff line; a reflector, which reflects a light from the light source toward the projection lens such that the light passes near an upper end portion of the shade so as to irradiate a forward direction along an optical axis with the light emitted from the projection lens; an overhead sign reflecting surface, which is provided near an upper end edge of the reflector and reflects the light from the light source; and an overhead sign light receiving surface, which is provided near the upper end portion of the shade and reflects the light from the reflecting surface toward the projection lens so as to irradiate upward irradiation light from the projection lens. The overhead sign reflecting surface includes a plurality of reflecting surfaces, which emit reflected light of different patterns.
