OK, I have noticed many posts and complaints about bow lights. Ours started giving me trouble recently and despite typical bulb replacemnt, greasing the O ring seal and cleaning it continued to stop working or get condensation inside. I decicded to investigate further. Our Nantucket 190 lens is plastic with plastic feet that lock with a twist into the base assembly. Then a chromed metal cap installs over the plastic lens and two screws hold it in place. The thing is that I discovered is that the plastic feet on the plastic (green/red)lens are broken and this allows the lens to float up ruining bulb contact and allowing water past the O ring. Hmmm, why doesn't the chrome metal cap hold the lens down--hmmm--it does not--the broken plastic feet are supposed to. There is a gap between the cap and the lens. OK, go get some plastic stick on feet (like for stereo equipment to prevent counter scratching) from Home Depot--the clear silicone ones are nice. Take one and stick it to the inside center of the chrome metal lens cap. Now when you install the cap over the lens the cap will press down on the lens preventing it from popping up (which it does because the plastic locking feet are broken and missing)and thus maintaining good circuit contact and keeping the O ring sealed to stop water from entering. Works good now.
