Re: bennington navigation light
Hopefully just a bulb, but there's no way to know for sure until you look at it. Can the boys not tell you anything? Fuse is unlikely since nav/anchor should all be on the same circuit. If it were the switch the green would be out too. Guess that just leaves bulb, broken wire or connection, or corrosion. Find out what bulb it needs and take a couple with you. Also take a couple of fuses in case you blow one, and take some basic eletrical tools; strippers, crimpers, connectors, tape; that sort of thing. My money's on a bulb though unless it took a hit from a dock or something; of course in that case it could still be the bulb.
