I see dozens of newbies patching together LEDs for aircraft lighting and am frequently mortified. Remember, when your family gets called and told that another plane with homemade night-lighting killed you, everybody carries some blame for letting it happen.

Item: It is theoretically impossible to build a tail light using LEDs that draws 200 mA and cost $89. Strobe too! And it won't even be possible when my now preschool grand-kid graduates from MIT.

Item: It is theoretically impossible to adjust 26 tiny LEDs to form a position light, even if the peak candelas times 26 comes out to some kind of legal-sounding number.

Item: I quit selling LED position lights (but still sell a few tail lights), that really are legal. I just could not compete with the claims of the poor quality stuff. In fact one of my customers, having lost his regular landing lights, landed at night using ONLY the LED position lights for illumination. This might have been a historic landing.

See attached.

Did you ever take a look at "Jeff's" LED wing tip position lights (and
regular strobe) for RVs? If so, what did you think?

No specs here. "Jeff's lights are no longer available as far as I know.

Jeff's look very nice--they probably are per FAA specs position lights. I'm less sure of the strobes, but they could be okay. Exquisite workmanship.

Can't tell more without closer inspection and specs. Some images don't want to load on my computer from his website.

Thanks. I know there wasn't much info there but appreciate the reply.

Those images don't load on mine either. I think these pages have been
un-maintained for awhile.

I'm happy with them except for the noise from the pucks. Will be
installing Bob's quiet power supplies to fix the noise.
