Abstract: A light module for use with a plurality of light sources mounted to footwear, includes a power supply, an oscillator circuit, a power supply transmission circuit and a switch. The oscillation circuit supplies power to the light sources to sequentially cause illumination of the light sources. The switch has an open condition and a closed condition. A power transistor of the power supply transmission circuit has an input connected with the switch, and an output path connected between the power supply and the oscillation circuit for supplying power from the power supply to the oscillation circuit when the switch is closed and for terminating over time the supply of power from the power supply to the oscillation circuit when the switch is open. A bypass circuit includes diodes connected between the oscillation circuit and the switch to disable the oscillation circuit in order to continuously illuminate the light sources when the switch is closed. The bypass circuit is disabled when the switch is open.

Abstract: Flashing footwear includes at least one light source, e.g., an LED, located on an external surface of the footwear so as to be visible, such as the rear of the heel. A power source, such as a battery, provides sufficient power to light the light source to cause illumination in response to a switch actuated by the condition of motion of the footwear so as to change between open and closed positions. A circuit is combined with the battery and switch to form a module arranged in the heel of the footwear. This circuit directs power from the battery to the LED to cause the LED to illuminate for a period of time in response to a change of the switch from the closed position to the open position and/or to light continuously while the switch is closed.
