Glad you guys found this useful.

Our DAR says that they don't make specific demands regarding how something is
done, so LEDs are fine as long as they are bright enough and have the necessary
visibility pattern. He saw no problem whatsoever using LEDs for these lights.

I noted in one of my aviation mags that Whelen has a $700+ vertical stab. LED
strobe light! Probably doesn't include the power supply. This is obscene and
could easily be done with a set of Luxeon 5-watt white LEDs in a circular pattern.

Some 3-rd parties are trying to market various combinations, but unless you need
very special hardware, you can just make these yourself at a fraction of the cost.

Good luck.

That is the best eaa site I have visited.

Guessed which was the LED story and read it all.

Good job.

Last week, I attended the farcical FAA-sponsored maintenance seminar and the GE
lighting people were there for the first time.

I had a good discussion with them as to why the Q4509 bulbs burn up when used
continuously as so many do these days (not designed for continuous, and never
tested that way and a surprise that people use them as get out of my way
lights) and they were queried about LED's and the "blue lights" which are such
a pain when on cars.

LED lights are being "looked at".

The blue lights (high intensity discharge) are being evaluated but they have
found too few willing to pay the high prices for it to be a product for
them...yet.

Thanks for the site info and the lead to the article.
