The idea of having ‘navs’ or position lights on your plane is so that other aircraft can see you coming, and work out appropriate evasive action if required.
The simple question is, how far away do you want to be seen from?
We took a Flyleds demonstration kit to the Oshkosh fly in this year. In the photo below, the Flyleds demo box is sitting on the ground below the wing of the plane. The plane has another ($$$) LED product fitted to the wing. The Flyleds box is admittedly both the red and green LEDs in the one small area, but as you can see, our phone camera just couldn’t cope with the brightness and has called it white light (it was otherwise pitch black). There is a ghost image of the Flyleds box near the wing root caused by lens flare that shows that this is the position lights only, and not the strobes in operation.
So, which would you prefer to be; invisible or visible to others?
