Abstract
Abstract A solar powered construction light 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 construction light during the dark or twilight hours when construction lights are commonly employed to warn motorists of road hazards.
