Hi Dave,
I have the Duckworks LED wingtip lights installed in my wingtips.

I just had a look at my build-log and it was November 2013 when I installed them.
They are well made and mount easily in the tip.I use them as my Taxi Lights as they are only 1500 Lumens. They are hooked up to my VP-X for Wig -Wag on final.
Three years is a long time in LED technology and I would expect that these should be due for an up-grade LED soon.
I have the Duckworks HID's for my Landing lights and plan to upgrade them to the Baja XL80 (9500 Lumens ) at a later date.
Cheers,
