Question Red Over Green

The USCG refers to various "occupation Lights" for commercial vessels. Categories include RAM (restricted in ability to maneuver), NUC (not under command), Pilot, etc., etc.

They also allow a Red Over Green top-of-mast lamp for a sailing vessel. I have never seen this displayed on the Great lakes, and don't know where one would buy such a unit.

Maybe the Masthead TriColor is more popular, but I know that if a TriColor is lit, the USCG requires that the regular sidelights and sternlight must not be displayed simultaneously. However, they do allow a red-over-green to be on at the same time. So you can legally run the red-over-green Occupation lamp at the same time as the regular sidelights and sternlight.

In the interest of being seen at night (especially when heeling, or the sidelights are obscured by a large Genoa), and particularly when racing, or when on large seas, or near shipping lanes, the red-over-green occupation light seems prudent.

Does anyone have a source where these can be purchased?
