So in my 2019 JL Unlimited, the only "ambient lighting" this controls is in the drink cup holder....I need to figure out how this function works. When I'm in the vehicle with the exterior lights on and move the Ambient Lights knob...nothing happens. I can't see any variation in interior lighting, even in the footwells. Maybe I just need to be in a really dark environment to see a difference. I actually haven't driven it much after sunset, so not sure how much I would notice anyway.
