Hello - I've been gettting quite a few PMs asking about the materials used to make the LED nav lights. Here is the scoop:
Here are the resistors you need:

here are the Green LEDS: (use cyan, not green)

here are the Red LEDs:

The luxeons should be mounted to an AL sheet with heat conducting, but electrically insulating compound:

Mirrored Plexi can be found here:

Here is the schematic:

Questions:
Do they meet the FARs? -
No idea - but they are crazy bright
Do they get too hot? - Mine have not - I run them whenever I fly - no issues in almost 400 hrs - the resistor tends to underdrive the LEDs. The resistor gets warm, but not hot.
Total cost? -
LED prices seem to vary a bunch - I have about $60-$70 in both sides of mine.
My standard 1 beer fee applies - payable in the upper midwest (during the summer)........
