A couple years ago I first saw the beautiful and incredibly robust Lopolight LED navigation lights at Strictly Sail in Miami. Happily, I see they are now available from Ahoy Captain, a great online catalog site for high quality voyaging products. They carry what looks to be the full line, with everything from masthead tricolors, to sidelights, anchor lights, etc. They are not cheap, but by all appearances, they should stand up to most anything nature can dish out.
