A solar powered warning light device includes a housing having a front orifice, a solar panel disposed on top of the housing to receive solar energy, a circuit board disposed in the housing and having a converting device coupled to the solar panel, to receive and to convert the solar energy into electric energy and stored in one or more capacitors. The circuit board includes one or more light devices coupled to and energized by the capacitor, and engaged in the orifice of the housing, to emit light out of the housing. A switch may switch on and off the light device, and a photoactive member is coupled to the electric switch, to operate the electric switch by the light of the environment.
