ABSTRACT:
A solar powered warning light apparatus including a solar module that charges a single rechargeable Ni-Cad battery is operable for intermittently flashing a xenon flash tube. A recharging network of the apparatus allows the solar cell module to recharge the battery when sunlight is impinging upon the solar module for providing virtually maintenance-free and long term operation of the warning light by the battery during the dark or twilight hours when warning lights are needed to warn vehicle drivers of road hazards or environment hazards.
