Current lighting is clamp on flashlight with the red/green split. Anchor light is broken but was the same setup. Would like to go all LED to preserve the battery. Having a cable slap around inside the mast would drive me nuts. Is there some way to keep it from doing that? I thought about shooting expanding foam in there, but I'd want to put the wire in a plastic conduit in case there was a problem later on. But that all adds weight to a mast that I raise and lower solo, "Armstrong" style. It would also make the mast buoyant, which is a plus.
And since I'm going LEDs, why not keep it light and cheap and use 4 conductor telephone cord? There's a good way to plug it in too! Not exactly waterproof though...
Thoughts?

I've heard of people using expanding foam in the mast. I don't think it's very heavy and it is good flotation. It would eliminate your worry of the wire smacking about. The hard thing would be getting the foam far enough down inside the mast. I'm not sure how you would get it much past about 3 feet in. If you're not as concerned with flotation, but want to restrict the movement of the wire, you could fabricate some disks out of styrofoam that would slip over your conduit tightly, and shaped like the inside of the mast, so it would slide down inside with the wire and wouldn't allow for flapping around.
