ABSTRACT:
A safety light for a bicycle. A housing member supports a power source and at least one light source. The light source is electrically connectable to the power source. A motion sensitive switch switches between an open condition and a closed condition in response to motion of the housing member. A control circuit is activated dependent on the open and the closed condition of the motion switching means. The control circuit produces a flashing voltage pulse effective to cause the at least one light source to flash on and off. The control circuit also detects an on-off cycle each time the switching means switches between the open condition and the closed condition in response to motion of the housing member and produces a flashing voltage pulse for a predetermined length of time after detecting a last on-off cycle. In another embodiment, the power source comprises a magnetic member for providing a magnetic field and a conductive coil disposed relative to the magnetic member so that motion of the magnetic member relative to the conductive coil in response to motion of the housing member produces an electric current. In still another embodiment, the power source includes piezo-electric elements which generate electricity when struck by a moving weight. At least one light source supported by the housing member is electrically connectable to the power source for receiving the electric current in response to motion of the housing member.
