Tim, I've done a little more research, it seems that their US distribution is done through
Novita Technologies, which is based in Hendersonville, Tennessee. The parts themselves are identical, though, and the Tridon flashers I'm using are USA made. I did find a
6 volt flasher on the Novita site.
I can't say about 6 volt, but I've had no trouble getting the 12 volt versions locally.
