Thanks John for a very complete answer.
I purchased a set of Whelan Microburst III wingtip lights for my Kitfox I am now building. They have the red & green lights, a steady white light showing only to the rear, and white strobe lights which can be turned on separetely. The lights are not certified and are only for experimental use.
It sounds like from what has been written on this thread I will be Ok to use them on my experimental at night if I have a full private pilot in the plane (I myself will only have a sport pilot cert). Is my thinking correct?
Jim
