It is well known that riding a bicycle and crossing the street at night is dangerous. In order to prevent corresponding traffic accidents, we introduce the use of Safety Light. It is a LED light band which sticks to a set of wheels. Based on the character of persistence of vision, we believe that a succession of rotational green marks which give drivers or passengers impression of motion helps reduce accidents.
