The present invention produces electricity from solar during the day using solar cells and stores it in the battery. On night or cloudy days, the surrounding illuminance is automatically sensed through the solar cell to detect the MCU (Micro Control Unit). No power supply is required, and there is no burden of electricity costs. In addition, it does not require construction costs such as electrical wiring, and is easy to check and repair through the home cover (3), and it is possible to save energy because it is generated by solar, which is natural energy, and when the battery is used as a super capacitor, It can be used semi-permanently and can have the effect of the main body (1) octagonal shape, even if the solar road sign bottle is broken by the vehicle, always maintains the origin and significantly reduces the twist or fall out of the cross-shaped prop 201. Prevent secondary accidents. ; MCU (Micro Control Unit) Road Sign, LED Sign, Sign Bottle
