Abstract
Flashing footwear includes at least one light source, e.g., an LED (12A), 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 (28), provides sufficient power to light the light source to cause illumination in response to a switch (26) 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 (28) and switch (26) to form a module arranged in the heel of the footwear. This circuit directs power from the battery (28) to the LED (12A, 12B, 12C) to cause the LED (12A, 12B, 12C) to illuminate for a period of time in response to a change of the switch (26) from the closed position to the open position and/or to light continuously while the switch (26) is closed.
