Abstract: A chain-control device for solar road studs is provided to work by using a plurality of solar cells to convert solar energy into electric energy during daytime and store it in a battery unit, so that they can flash in nighttime for traffic security purpose or gardening deposition. The primary merit of the present invention is, first of all, free of wiring job, no need of city power, good conformity with environment protective conditions. Because of a successful chain control function, the existing random flash performance could be substituted with an interactive chain control flash or a synchronous flash performance, which is also applicable to gardening for fancy flash performance.
