There is already a light inside the case when you open it, at least there is in my 2020. The light only works when the ignition is turned on.
And the USB port in the back is also keyed to the ignition.
On earlier models, there was a way to make the power ports live all the time by shifting a fuse. I don't know if that works with the newer generation.
If it ain't broke, don't break it.
