Thanks to all the suggestions. I contacted Defender and they were able to special order the light from Perko. Perko does not sell direct and while I was researching Perko the parts required to repair the light (damaged during un-stepping the mast) cost almost as much as whole new unit.
I also had two other posts, 1 from Tonga looking for a Stem fitting and upon reaching Pago Pago, American Samoa, I contacted the Beneteau Syselios parts site (thanks to Ron2034 for the suggestion) and was able to have a new one sent right away from France. The other post about wear of the mast base in the deck step is in progress at the moment. In Hawaii now, pulled the mast and am replacing the rigging. The rigging was out of tune, (too loose) and the Forestay has broken wires at the top fitting. Mast rake was too far aft and allowed the mast to move in the deck step, wearing it away with the movement. No corrosion at all. Cut the worn part off (shortening the mast by 3/8") and while the mast is off replacing all the rod rigging, forestay and backstay and all the wiring. I am fortunate the forstay did not give way on the return to Hawaii from American Samoa. The rigging is, to my knowledge, at least 19 years old and it was time for replacement. Thanks to all for your comments and help. Also have need for info/suggestions for replacing the Wago rail mounted terminal blocks which has problems with corrosion. I'll start a new thread on that subject.
Thanks again.
