mine too
Mine has been running on the tail of my RV 9A for almost two years now. It is on full time when the avionics switch is on. That is quite a bit of duty time, since I fly the plane for work several days each week. It is sturdy, bright and reliable. I did not build mine, just bought it completed and did the conversion from the original tail light fixture.
No one has ever noticed the flash is spelling out a message. Anyway, good product and priced very reasonably. Check it out....
(I was in Australia all last week.... but did not have time to go check out the production facility.... maybe it is just a garage anyway! ) Cheers.
