Recently I posted some questions regarding this issue. After some
experimentation, it appears that LEDs and inexpensive strobes are indeed
a feasible option for experimental a/c.

Following a presentation at our recent EAA meeting, our most senior DAR
liked the mock-ups so well that he will install some LEDs on his own
plane! He has no problem approving an appropriate LED/nav installation
as long as the visibility geometry is appropriate.

To see an article on using LEDs and inexpensive strobes, feel free to
visit our EAA site, scroll down to the member news area and click on the
obvious link. http://www.eaa724.org/
