EXCELLENT response! Sounds like the "transponder" option is to get a
Zaon MRX http://www.zaonflight.com/mrx.html It's better if I'm AWARE
of ALL the transponders nearby instead of just trying to become visible
to a few others with limited success.

Did a quick Google search for LED strobes and these are intriguing, but
looks like 1/3 to 1/2 amp drain, so even worse than transponder. But,
it may be possible to rig these to flash less frequently...
