Abstract: A step triggered light up footwear device that creates a flash of one or more lights when a wearer moves or takes a step. The device includes a body with a battery holder, a battery, a manual switch, and a motion sensor. It includes a first light-emitting element, a second light-emitting element, and a control circuit connected to and powered by the battery. The control circuit is also connected to the first light-emitting element and the second light-emitting element, and may be further connected to receive inputs from the manual switch and the motion sensor, such that operation of the manual switch causes the control circuit to provide power to light the first light-emitting element for a first time period, and such that a motion sensed by the motion sensor causes the control circuit to provide power to light the second light-emitting element for a second time period.
