Does anyone have any experience with their led strip flickering on startup and not lighting up.

That is interesting. I'd start with unplugging connections and inspecting pins for damage, growth, burns, discoloration. Unfortunately I don't think you can reach the the main connectors at the head lamp housing easily.

Once lit, do they stay on?

 

That isn't my vehicle, just a example but in my case. I have one side that I bought as a loaded set from Sewell which works fine. My driver side was damaged so I bought one from local dealership here and I believe it's a stripped version. The new one flickers like that in the video and does not light up at all, all other lights in the housing works. I think it just needs to be rewired ?

 

What year is your car? If it's a pre-2011 or 2011+ that came with halogens, you cannot just buy it from Lexus and plug it in, you will need to rewire it. In the video, it is a 2006-2008 car as well.

If one side works, make the wiring on the other side match it.
