Great replacement for older troublesome flashing units. If the light is on solid it is wired backwards. The plug comes from the factory backwards from some Cessna plugs.

Easy to install. Very Bright. I would have given this 5 stars but the I believe the item is over priced!

Lots of positives: light weight, easy to install, relatively low cost. I changed the stabilator fin cap because of smaller diameter. However I was surprised to have greater RFI than the HRCFA strobe I replaced. I did not expect this at all. I could barely hear the strobe in my radio (garmin 200), but now there is prominent noise. Perhaps it is not as electrically simple as it looks.

The light works well, as expected, but it does NOT come with the adapter plate shown in the picture. That needs to be ordered separately for an extra $90.

nice NOT led beacon. better than the factory beacon on the early Cessnas as less amps and you get to remove the power supply which is another source of failure on the old beacons. But, way to expensive for a plastic base, plastic lenses, plastic base to bulb, and Its still just a halogen beacon with 80$ replacement bulbs. if you can, double the money for the LED. I know......frustrating.:)
