A shoe lamp device with multiple voltage levels comprises a plurality of single color light emitting diodes; at least one diode emitting light with wavelength below 5200 angstrom (AÅ) by using a power supply having a voltage above 4.5 V; a power source including batteries for supplying power to the single color light emitting diodes; a vibration switch for generating a trigger signal when the vibration switch vibrates; and a substrate having an IC control circuit; the substrate being electrically connected to the single color light emitting diodes through conductive wires; when the circuit receiving a trigger signal, it will generate a driving signal to drive the single color light emitting diodes to flash according to a predetermined sequence. The voltage of the power supply is 4.5 V (volts) which is formed by serially connecting two batteries of 1.5V and 3.0V, respectively or the two batteries of 3.0V and 3.0V, respectively.
