PROBLEM TO BE SOLVED: To provide a marker light in which the device thickness can be suppressed by a simple structure, information displayed at a display part can be easily recognized from the outside by transmitting the light from the display part for emission, and an outside-originated light emitted from the outside can be reflected to the direction from which the outside-originated light is emitted.SOLUTION: A marker light comprises: a light source part which emits light; a light guide part which is adjacent to the light source part and emits from a principal surface the light of the light source part coming in from the side surface; a transmission and reflection part which is formed by lamination on one principal surface of principal surfaces of the light guide part, transmits a part of the light emitted from the principal surface of the light guide part and reflects an outside-originated light emitted from the outside; and a display part which is formed by lamination on the transmission and reflection part, displays specified information and transmits the light from the transmission and reflection part. The transmission and reflection part is constituted by reflection parts in each of which a reflection film of a triangular-pyramid-shaped concave part is formed and a transmission part provided between the reflection parts, and the reflection parts are formed as matrix-like with specified gaps. |
