PURPOSE:To perform light radiation within a wide angular range in the circumferential direction so as to improve the visibility of a marker lamp which is formed into a cylindrical shape. CONSTITUTION:A lighting fixture main body 10, and a lens 19B constituting an approximately cylindrical lighting fixture housing together with the main body 10 are such formed that a cross section has a center angle larger than at least 180 deg.. The lighting fixture main body 10 is intruded into a cylinder of the lighting fixture housing. In the intruded portion, a light source (bulb) 18B is supported in a cylindrical axis position of the lighting fixture housing. The center angle of the lens 19B is large and the lighting fixture main body 10 is not overlapped with the lens 19B in the circumferential direction, thus realizing light radiation over the whole angle of the lens 19B so as to provide visibility within a wide angular range. |
