5 KC's to one switch

All the lights would be wired to 3 relays which would then be wired to the switch. The relay is like a switch in itself but it allows a lot more current to flow through it. Rather than "switching" a relay like a light switch you wire it to a switch in your truck that triggers the connection.

I'm not sure what wattage the lights you're getting are. The rating of the relay will determine how many relays you need. Using the 125% rule:
100 Watt lights: 45 amps
(3) 20 amp relays
(2) 30 amp relay
150 Watt Lights: 67 amps
(4) 20 amp relays
(3) 30 amp relays
The high current feed to each relay should be fused according the the relays current rating. A 30 amps relay gets a 30 amp inline fuse feeding it. Do not just put one big 60 or 80 amp fuse and split to each relay. You can very easily cook the relays or burn the wires and your truck down if something shorts or is not working properly.
