There are some fairly specific rules regarding navigation lights, but not so many with strobes. Jim Weir recently started a series of Kitplanes articles on how to make your own LED nav and strobe lights, and one of the things he said about the strobe regulations are that they are vague enough to drive a truck through. I've never seen an FAA guy with a lumen meter either. But one hard and fast rule is that you have to be able to see them just about all the way around, so one strobe on top may not get you there, although that would be a pretty close second. Don't take my word for it though...seek out the regulations and check. And if the plane is already built and you add them to an experimental, the builder can add them and be night legal with a logbook entry. Mark Langford, Harvest, AL ML "at" N56ML.com www.N56ML.com
