A wind power driving auxiliary lamp comprises a seat, a generator, a transparent cover and a circuit device. The seat has two supporting frames. The generator has a blade set and a small power generator firmly secured to a blade groove of the blade set. The blade set and the small power generator are positioned between the two supporting frames. The blade set and the small power generator rotate synchronously. A circuit device includes a circuit board in the transparent cover and a light emitting body set on the circuit board. In moving, air will push the blade set so that the small power generator and the blade set rotate synchronously, the small power generator will rotate with the central pivotal shaft so as to generate direct current power to be supplied to the light emitting body set.
