To give a warning to a pedestrian and a vehicle by providing a transparent resin plate on an upper surface of a metallic casing arranged in the same height on a road surface, and installing a block to house a storage battery and a chacharge/ discharge controller having a waterproof structure and an LED light emitting element block.

A solar battery protective plate is worked in a circular shape, and a screw hole is bored on an outer periphery, and a casing is arranged, and an O ring 25 is put in it, and the solar battery protective plate is screw-fitted to it, and waterproofness is secured. A cylindrical lens is arranged in a light flux guiding cylinder 32 for a light emitting element 31, and the light is effectively radiated outside. When a moving body approaches within a specific distance range of a light emitting element 31, a light emitting flashing frequency by the light emitting element 31 is increased by sensing of a light sensor, and a danger is warned against a pedestrian and a vehicle. A quantity of light is increased in a time zone of a dangerous zone within a capacity range of a solar battery and a storage battery, and it is utilized for previewing a danger. Therefore, a warning radiation light quantity is emitted and radiated on a horizontal plane, and a light emitting part unit is arranged by a light emitting color, and the solar battery protective plate is reduced, and a cost can be reduced.
