Here's an example of one of the ones I make. This one has no ground wire because it's for a Polycarbonate Plastic signal. Not legal (I know) but IMHO better than the hacked one it had.
One or two layers of Scotch Super 33+, depending on use (hanging loose or running through a stand through two 90s, respectively) over 14, 12 or 10 AWG stranded wires, depending on which Handy Helper cuts the wire for me. My standard color code is Red/red light, Black/yellow light, Blue/green light, White/neutral, and a green ground of course (except in the case of poly lights.) This varies depending on the number of lights.
