Abstract: An illumination device that is mounted on the distal end of a flagpole illuminates a flag displayed during periods of darkness to conform with common flag etiquette procedures. The illumination device is powered by batteries during an illumination mode of operation during periods of darkness. The illumination device enters a charging mode of operation and charges the batteries with an embedded solar panel during periods of daylight. The illumination device is configured to attach to the flagpole using a threaded receptacle in such a way that it is easily installed in place of a flagpole finial or ornament.
