Abstract
An underwater lighting fixture adapted for installation in a wall of a swimming pool. The lighting fixture includes a housing having an interior cavity and a transparent cover. A color changing electric light assembly is provided in the interior cavity. The light assembly emits a plurality of different colors of light through the transparent cover and cycles through the plurality of different colors of light to sequentially emit each of the plurality of different colors of light. An electrical conductor extends through the housing into the interior cavity for delivering power to the color changing electric light assembly. A synchronization circuit responds to a timed interruption in the power for synchronizing the color changing electric light assembly with a color changing electric light assembly of another underwater lighting fixture connected to the same power.
