To provide an omnidirectional warning light which can display a substantially spherical shape even if viewed from any direction of 360°, has simple structure and has an easy fabrication process.
A number of conical pores are formed on light guide plates 1-1 to 1-24, the light of an LED light emission source is applied from upper and lower sides of the light guide plates 1-1 to 1-24, reflected on boundary surfaces between the light guide plates and the conical pores, and thereby, the light of LED is displayed from surfaces of the light guide plates 1-1 to 1-24. A number of the conical pores are arranged in a semicircle on each light guide plate 1-1 to 1-24, reflection light by means of a number of the conical pores is output horizontally and the substantially-spherical red color display can be achieved even if viewed from any direction of 360°.
