"I'm using 12 volt for motors and 4.8nvolt 1100mah for receiver. suspect will have to add something else for lights?"
OK, thanks Austin, gives me food for thought.
You should not need an extra battery for lights, unless of course you need some more ballast anyway. I always prefer battery ballast to dead lead ballast 😉
We should be able to tap off those two batteries to feed the lights.
For RC switches to turn 'em ON/OFF have a look here for some inspiration!
There must be some decent Canadian/US suppliers of similar switches as well.
First thing to do do is work out which lights belong together and thus how many circuits / switches you will need.
Then we can work out the voltage dropping resistors needed to tap off your batteries for the LEDs in each circuit .
An alternative could be to use a voltage dropper circuit (or so called UBEC) to provide a lower voltage supply, from the drive battery for instance.
