Hello Everyone -
I know this has been discussed in other forums, but I can't find anything recent... I'm not searching very well apparently.
Anyway, I know some folks have been looking to modify their lighting to LEDs. I bought my M20F 6 months ago and the previous owner had a field approval -337 for AeroLED lights on the wingtips and tail. They are awesome. Very bright, don't draw any power, last forever, good warranty, and good customer service. Reading the paperwork, I think they are made by Aviat, but marketed by AeroLED.
The wintip lights have white strobes and red/green nav lights combined. The tail light has white/strobe.
At the same time he had the LEDs installed, he had the beacon removed (that's good for 1 knot, right?).
They are available on Spruce or direct (I think). Yes, they are expensive, but I am glad I have them. The company is in Idaho and I've had to talk to them twice. They have a 5 year, 50,000 hour warranty. Unfortunately, one of mine had some kind of leak in it and got a bunch of water in it after an IFR flight. It still worked, but I sent them a photo from my phone and they shipped me a new light with no questions asked. Easy.
Anyway, I'll attach a picture (it's the one with the water in it). Let me know if you have any questions.
I also have the Whelen LED landing light which is equally good.
