You need relays. each light is pulling 8.3 amps and most relays can handle 30 amps. All of your lights running will be pulling 50 amps. I don't know if they're all facing forward or if you have one or two facing backwards. If they're all facing forward: Run at least 2 8ga wires to two different relays, then up to the lights and have 1 14ga to each light. If having 2 lights facing backwards: run 1 6ga and 1 10ga to 2 different relays. You can figure the rest.
