A light assembly comprising a light-emitting diode (LED), a rechargeable capacitor to energize the diode, and a solar cell to recharge the capacitor. Preferably, there is circuitry to enable charging of the capacitors and circuitry to enable use of the solar cell as a photosensor to selectively energize the LED when the ambient light is below a pre-determined level, and to stop energizing the LED when the ambient light is above a pre-determined level.
