hi Shane.
that looks like a lot of un-nessesary umbilical wiring. i'd reccomend using a multiplexer of some kind, velleman kit or something similar so you can have a much thinner tether for the same controll. also the cameras need power, or are you supplying this down the coax.
hope this helps and is not just criticism. ;-)

The LEDs need some sort of current limiting too, at the very least a resistor in each branch, but better still a proper driver circuit. drivers are cheap as chips from china.

well you are only putting 6v across 4 leds, so you don't really need a resistor. what is the forward voltage of each led?

you can buy already some 6-12V car LED Lights. I bought a chinese product 12V, 18 Leds for about 30$ each (I use 4 of them) saves a lot of soldering and mounting, just plug and play..
