Thanks for all the help. Still could not get the LED's to work. May have burned up the lights output on the LCRX.
Going to plane "E"
Plan "E" is install a ERR Mini Commander EX in the MP-15 dummy and use the LCRX in a F7B for railsound(no lights in the F7B)
I have had good luck using my LED's in ERR DC Commanders so the LED's should work with the Mini Commander.
