A few suggestions I uncovered that I have had success with over the years....

1. Cheaply constructed lights on a boat tend to collect condensation on the inside of the fixture. Always had moisture in it. The solution was simple and cheap. A little grease on the threads of the lens sealed the fixture. No more condensation. Go to the auto parts store and get a tube of di-electric grease and coat the base of the bulbs this will help prevent corrosion and will displace water form getting to the sockets also helps with vibration.

2. You are right about water contact blowing the bulbs. Upon closer inspection, the two tabs for the wire hook up protrude thru the base of the housing and this hole is open into the cavity that the bulb is in. So, splashling water or waves that hit the bottom of the deck could introduce water to the hot bulbs. Sealed the opening with rubber gasket with slits for the wire connectors.

Finally, the other thing I have done is to take a small piece of sandpaper and sand the contacts and metal inside the fixture to remove small amount of corrosion.
