I figured out the lights on the JJRC H8C is channcel 5 in case someone needs to map theirs.

It's a H8C config file for devo8s, it should work on devo10.
light ch5 = mix switch , off , blink , on
flip ch6 = fmode switch
video ch7 = ELE DR switch ,0-1-0 on/off
picture ch8 = AIL DR switch, 0-1-0 on/off
