The older deck and spreader lights had burned out so time to go up the mast and replace them. We went with the Forspar ML-1 LED Deck lights for the spreader lights and the COMBINATION DECK/STEAMING LIGHT– ML-2 the ML-2 is not LED as it is a running light and on only when motoring. We also read a bit about issues where the motoring light could get knocked off by halyard or sail so we purchased and installed the Mast Light Guard as well.
I should have paid more attention as I knew the batteries were close to end of life and as one died it took the battery charger with it. Batteries are already expensive enough but add to that a new battery charger. I went with a ProNautic 1230P http://www.promariner.com/en/63130.
