[wireties]

The insulation on the ring lights is so soft we stripped them with a fingernail!! I would NOT solder them as that insulation will melt quickly. We stripped them, folded the bare wire over itself so it is thicker, crimped it in a butt splice, crimped the other end to some 22AWG cable and ran it to the M+ and M- terminals of a spike so we can turn it on and off. The GND and 12V terminals of the spike go to the PD board.
