Looking for advice on LED position lights

#1 Post by ctmorawetz » Tue Sep 19, 2017 8:28 am

Does anyone have experience replacing incandescent bulbs on a 172 with LED position lights? What do you recommend? Thanks!

You can't just order up some new LED Nav lights as installing them would constitute a change in the type design. In this case I would think that it is a major modification per CAR 571.06, which means that you would need an STC to approve the installation of LED nav lights. There are some business jets I've seen out there with LED nav light STC's, but I've not seen an older GA aircraft out there with them. Mind you, I haven't been looking either.

There are actually numerous retrofit options - Whelen, Aveo...

STC's are available to cover just about any LED swap (Nav, beacon, strobe, taxi, landing, etc). I believe some are even PMA replacements, no STC required.

^ This. Just like Taxi/Landing Lights there are basically drop-in LED replacements available.

Whelan lights are STC'd for most common GA aircraft already. They fit right in to the current installation. Only thing to remember is they are polarity sensitive

Have done the change many times with Whelen parts. Straight up replacement and no STC needed. As said before, just watch the polarity.

ct,

The advice you've been given here is good. If it won't work, you can PM me. I've STC'd these before.

Only legally an option on amateur-builts, I expect. NavStrobe lighting "...have been designed to meet the requirements of TSO-C30c." ie. they believe it meets requirements, but they've never been formally tested for approval. The Aircraft Spruce page has a Q&A tab where this is addressed as well.
