Replaced masthead trilight, LED bulb

We purchased a FirstStar LED trilight bulb, which is conveniently a light-activated anchor light and trilight all in one bulb that fits a standard socket (only two conductors needed; switch the polarity to switch the function). Our old masthead housing wasn’t a standard socket, and was nearly opaque besides. We replaced it with a standard Aqua Signal series 80 fixture. But we weren’t happy with how low the housing sat–the visibility was blocked by other mast hardware. So jonny bought some c-board and we mounted the fixture atop four stacked 1″ pieces of c-board. I even routed the wire through the c-board to come up exactly underneath the fixture, to avoid water intrusion. We’re very proud of the result.
