First thought is: Not a good idea! That said, I started with the creative aspects to try and show some respect for the regulations. Lights could be made with red/green glowsticks. Would be neat to light the whole wing with something. Then red/green fabric patches could be sewn in the winglets. Night vision goggles would be a must for safety. Flying over water at the beach could lead to spacial disorientation, better to fly over a well lit area. i.e. Fly in daytime. Paint motor frame with glow in the dark paint. And lastly, have a bail bondsman on standby.
