Thanks, guys! They are indeed LED units. I pulled a car apart to make sure.
TBH, I'm not sure I even like having any interior car lighting. I don't really do night ops and the interiors being illuminated during "daytime" ops doesn't seem quite right.
Plus, it illuminates the interior to show that it's really not much of a detailed interior at all. With no illumination, the interior looks rather convincing.
All this coupled with the tendency to flicker kind of makes it all seem toylike.
I may end up removing/disabling these lights.
