ABSTRACT:
A solar powered illuminated yard maker including a solar powered battery recharging network that recharges a storage battery at a constant rate and can be selectively operated to burn continuously to produce a continuous light or to burn intermittently to provide a flashing light. A solar cell recharges the storage battery in the light when sunlight is impinging upon the solar cell to provide virtually maintenance free and long term operation of the illuminated yard marker during the dark or twilight hours.
