Typical Retro-reflectors installed on road have problems such as limiting a driver`s visibility at night when it is foggy or rainy. On the other hand, LED illuminated studs, called cat`s eye system, extends a driver`s visibility under these conditions. In this paper, we present a design of the LED cat`s eye system using solar energy that can sustain vehicles with about 30-ton weight and is compliant with the IP68 code for water proof as IEC standard 60529. In addition, we propose a scheme of designing a LED driving circuit consuming low power to take into accounts cold weather or rainy season with limited sunlight. This LED cat`s eye studs is currently installed and used on expressway and bike route nationally as well as overseas.
