BUT, you really need only a single pole three throw switch because you
only need to switch one of the wires, the other can go to both bulbs
all the time. AND again, you dont need diodes whether you are talking
DC or AC


If the switch is located at remote point - say on the boat's electrical
panel and the light is for example a 2-bulb steaming light/deck light, then
would your scheme not require 3 wires from the switch to the lights?

I have also seen diodes used - presumably they overcome this problem by only
requiring 2 wires up the mast?
