I might have an answer for you.
I fly a F550 frame, NAZA V1 and DX8. Due to my wiring, my AR8000 gear channel was the only channel I had left. My failsafe switch is the DX8 GEAR switch.
So I install this R/C remote power switch on the AR8000 gear channel to reset an OSD module. But since the failsafe is on the actual GEAR switch, when I activate failsafe there, the power is also disconnected from my remote power switch.
If you could have the remote power switch OFF, when activating failsafe, the remote power switch goes ON, which you have your lights connected to.
If you want more detail PM me and we'll talk and work out if it's possible.
