no, nav lights came on all at once with use of a single switch...and are steady burning, not flashing. i think thats what you mean by intermittent. :???:


found this interesting page where you can buy original vintage RAF aircraft lighting....you can see what they looked like. red, green, white, blue, and about halfway down the page are the red, green, and amber formation lights that you'd see on the undersurfaces.

amber white red formation lights on mustang (under wingtip):

Not quite sure what u mean by formation lights but I'm pretty sure those under the wings are for the engineers on the ground so they know what status the plane is in.
