Thought you may like to see the type of possibilities Spad.next gives you.
I added leds to the standard saitek switch panel. Using spad.next to program the leds with a PacLed64.
The switches and leds are programmable so that they interact correctly for each model of plane you use. This is with a DA40 so the light panel is available with the battery master switch in the off position. Since the landing gear is not retractable the standard front wheel led shows the park brake position. The blinking led above the landing gear is also programmed as the parking brake.
Hopefully this will give others some ideas for their own setups.
