Abstract
A multifunctional shoe flashing device includes at least one casing, at least one battery, a substrate, a conductive wiring, a lighting device, an oscillation switch, and a control circuit. The conductive wiring has one end connected to the substrate and the other end protruding from the casing and connecting to the lighting device, which includes three lighting chips. When the casing is affected due to external forces, the control circuit is triggered to activate flashing of the lighting device in a sequential and non-overlapping manner within a predetermined time period by setting predetermined mixed color and time ratios.
