Claude,

Thanks for posting this.

I usually search digikey and/or mouser for LEDs, but the Bridgelux LED
used here
is only available at Newark. I had missed it.

I bought a set of BRXA C1202 for my own wing tips, three on each side.

By my cacluation that easily exceeds FAA brightness requirements.

I have other LEDs pointing back.

I like the BRXA for several reasons.
1) it seems designed to operate in 14V systems. I used 0.5 ohm
series
resistor for each LED to limit the current, but actually I think
you could get away with out this.

2) has a rectangular footprint with plenty of heat sink area.

I will post some photos soon.
