You may and I say may regret not doing two different color LED`s as how can you tell which orientation of right side up with out some color change. Example rolls how do you know if you come out right side up? For my night flyers I always add white LED`s to the tail as then I can tell if the plane is coming or going, with out that for me I have know clue at distance.
There are some expose LEDs in the back plus from the front the lights are covered with the spar and leading edge. For when i do rolls if I pull up and it goes down it means I'm upside down. Pretty silly but we'll see how night flying goes
