Thank you, I just thought be on the same side. Overkill is my motto> I'm wearing a helmet, Elbow pads and Knee pads lol18awg should be fine. 12 is totally overkill for 700mA at the lengths of wire you will be using.
I would be more concerned about the wire's insulation jackets rating at the relatively high voltage you're using, at least for the red wire.
