PROBLEM TO BE SOLVED: To provide a marker lamp which can suppress thickness of a device with a simple structure, which allows information displayed on a display part to be recognized easily from the outside by making light transmit from the display part and emitting it, and which can reflect external light radiated from the outside to a direction in which the external light is radiated.SOLUTION: A marker lamp includes: a light source part for emitting light; a light guide part adjacent to the light source part and for emitting the light of the light source part made incident from a side surface from a principal surface; a transmission reflection part which is arranged on one principal surface side which is one of the principal surfaces of the light guide part, which allows one part of the light emitted from the one principal surface of the light guide part to transmit, and which reflects external light radiated from the outside; and a display part which is laminated on the transmission reflection part, which has a display board in which predetermined information is cut out along a contour, and which transmits the light from the light guide part. The transmission reflection part comprises: a reflection part in which a plurality of continued concave-shaped reflection films for reflecting light are formed; and a transmission part which is provided between the reflection part and the reflection part, and which transmits light. |
