An indication lighting device provided is capable of reducing the number of electric wiring from a fixed, part to a moving part when an indication part is provided in the moving part's side. The indication lighting device makes indication by emitting light from a light source arranged in a fixed part to an optical waveguide arranged in a moving part, reflecting the light incident on the optical waveguide by reflection surfaces of prisms of the optical waveguide to an indication part provided in a tip side of the optical waveguide to be propagated, and emitting the light propagated inside the optical waveguide through the indication part.
