I was thinking about Leds setup for a long time. Yesterday I analized one again all pros and cons and finally I took decision.

As you can see red lights are on back and status/intelligent LEDs are on back. It`s differnt than e.g. all DJI`s modern copters but I want to see red lights when it`s flying. I think simmilar pattern is use by Walkera drones and I like it. All setup is done, LEDs are well mounted and I think they will be working well during flights.

Maybe in the future I will change my decision and change current LEDs pattern but If I would need Pixhawk status on back I will add one status LED first. You can check how those LEDs works watching YouTube movie.
