In my 2017 there are three kinds of LED lights 1) the ceiling two sided LED lights and 2) touch bar LED lights that are over the beds and couch. and 3) beam lights over the beds and couch.
I am not sure if these are the same and if so, which type you are referring to, but FYI I had one of the ceiling LEDs become intermittent on one side. Playing with it I found that the LED PC board is socketed to the main base and that socket connection was very touchy to stay on. I got it to a stable place and plan to tape it to stabilize it.
