Experimental aircraft may not have to use certified lighting but I will assume that the lights used must meet the the same requirements written in the F.A.R.s regarding aircraft lighting for night flight.

Using these type lights for enhanced recognition seems reasonable after F.A.R.s for night flight lighting are met. In 50 plus years of flying I don’t ever recall seeing flashing nav lights and assume they would not meet the standard. I also personally would not use any color flashing light facing forward other than white and maybe amber but am not sure on the legality of amber either.

Curious what others think about other than white recognition lights. I think about how Draco is lit and all, other than nav lights, are white and face all directions. No way you could miss Draco in flight but few of us produce enough electrical power in our Kitfoxs to light all those lights.

Obviously a red flashing beacon is legal on fuselage or vertical stabilizer.
