I'm guessing that there is no response to this because no one knows how your pdb works to turn LED's on and off.  Several people have set up lost model buzzer though.  Just search the forum for buzzer or alarm or lost?

There is a kind of smart LED that we support called a WS2811 that changes colors and blinks different ways according to flight modes and errors.  Search librepilot.org to find the wiki and search the wiki for LED.
