I know this wasn't your question, but FWIW after reading your post I had to go out and double-check. My 2013 RX450h console interior does light up when the lights are on, the cup holders do not (but there is sufficient light from the overhead LED in pitch black that I can see a cup or something else is there to grab it.) I guess it's just another of those little nuances where Lexus has upgraded the 450h over the 350 -- strange when we find some of these things, but I won't complain.
