I have attached an article I wrote on first starts when I worked for Kitplanes magazine.
I didn't see where those LED lights are approved for installation.
Let me do some more research on approved LED lights and get back to you.

Hi Steve. Thank you for your advice. I do not think the aircraft ever had O2 as it was delivered to SD where it has been since 1981. I have been researching the portable O2 options and believe the Precise flight 4 person O2 is the way to go. I may have to add another 2 person because of 3 little girls that like to fly with me! The long term solution is calling Kent to see what connections he has regarding the retrofit. Thanks again.

Hola Steve, thanks for the feedback. Yes, indeed more work than I expected to do but somehow in the back of my mind I kind of thought some surprises might come up! Hopefully everything will work well, but I am planning for some things to present during the first hours.

I would love to learn more about how to run the engines those first hours, would you please share that information with me?

And one more question: One of the landing lights is burnt, so I am thinking about replacing both for these LED:
