OOOOOHHHHH-- wait---- these LEDs are picky I think-- if you don't get the wires right they flat out don't work, I THINK. With home runs, you can just switch the wires, but with one groundwire-- I think you may be in trouble. WhatDoYouThink?
Yes, LEDs care about polarity.
Pro tip: test all mast wiring
and lights while the mast is still on the horizontal and fixtures not yet screwed/sealed to the mast.
Then clearly label the wire ends at the mast base.
A splice around the steaming light isn't a problem as long as the splice itself is never subjected to a physical load. ABYC sez crimp please, you can then solder up the crimp if you like.
Best idea for waterproofing is to be able to slide a generous piece of adhesive-lined heatshrink over the completed splice. I've also had good results by gooing up the splice with 5200 or some other glue/sealant, then shrinking a piece of normal heatshrink down over that.
That tip from pcmm about including a piece of rope in the bundle is a good idea.
