Too bad this didn't do what you wanted. It seems like a good idea. Somewhere on the net, I found a rotating beacon using leds. The leds were bottom mounted, directed upwards at a revolving reflector. I believe that it was from Japan or Taiwan. The Tokyo Siren Co, Kyoto Industries, and Patlite all made incandescent or halogen beacons that worked this way, much like a Federal 27 industrial beacon.
