To provide a signal lamp capable of performing adjustment so as to reduce a reflectivity on a road surface, and a unit for a signal lamp capable of performing adjustment so as to reduce a reflectivity on a road surface.SOLUTION: A signal lamp comprises a light source and a polarizing unit provided on an optical path for light from the light source, and the polarizing unit has a transmission axis for transmitting vertically polarized light. A unit for a signal lamp comprises a polarizing unit that transmits vertically polarized light, and a transparent base material provided on at least one of a first surface of the polarizing unit and a second surface opposite to the first surface. The first surface and the second surface are provided on the optical path for vertically polarized light.SELECTED DRAWING: Figure 2
