I dont mess with light kits. I'm a racer, not a basher. Racers know they are illegal. If you dont know a thing about series of Parallel circuits, I dont have the pateints to go through it. Instead of purchasing the cheap LED's afigure out to set it up. Should have search for RC Flashing light kit with a module. It give you everyrhing needed to power it up to your RX, and it programable to flash. It'll look better then the octopus you have now.

Good Luck with your project.
