PA34 Owners Organization Forum Forums Aviation Interests Maintenance Position and strobe replacement with LEDs

Has anyone replaced the legacy position lights and/or beacon with LEDs? Were you able to use the existing power including the strobe power supply? (meaning it wasn't too much for the LEDs)

The strobe power supply isn't going to work for the LEDs - you'll need to remove this as the LEDs will run off of the 12v or 28v electrical system.

I asked Savvy this question a while ago (ended up buying a strobe power pack because I needed to get back in the air for my checkride, and here's the guidance I received:

For whatever reason, the Piper PA-34 is not on the STC for the Whelen Orion series LED NAV / Strobes. I typically sign these off as a minor alteration referencing Advisory Circular 20-41A in this case. You can review this with your A&P and see if they agree.

I think those units should cover it. You can eliminate the power supplies, but keep the harness and repurpose them to connect the new strobe lights and even keep the synchronization.

Great thank you

We did as the above for the beacon: removed the power supply and replaced with Whelan.

We also have on hand the Whelan LEDs which we are replacing the four outboard GE bulbs with - direct exchange - as the GEs burn out.

When you replace the wingtip strobes with the Whelan ones, use the spare wire to sync the strobes. I did all my exteriors lights with Whelan.
