Re: Converting Cabin Light Bulbs to LEDs
If the bulbs look like this, you can get them from Ancor, Perko ( manufacturers) at most marine supply places .
As for converting, I'd buy new fixtures and just wire em up. Your existing wiring is going to be heavy enough. In fact, you ma have to double or triple fold the light gauge wires coming off the LED fixture in order to butt splice them into your ( likely size) 14-16 wire.
I would go with new fixtures, not just LED lamps designed to fit into incandescent fixtures. These save some juice but you don't net the corrosion and shock resistance of led fixture and lamps.
This new ship here is fitted according to the reported increase of knowledge among mankind. Namely, she is cumbered end to end with bells and trumpets and clocks and wires. It has been told to me she can call voices out of the air or the waters to con the ship while her crew sleep. But sleep though lightly. It has not yet been told to me that the sea has ceased to be the sea.--Rudyard Kipling
