Like new steering wheel controls, pulled from my 2012 Pro-4X with 3000 miles. These are not illuminated, they do not light up.
I swapped lighted controls from a Pathfinder to my wheel.
There are a few good threads about adding these to your wheel, if your X didn't come with audio/cruise controls. Here's one I easily found: http://http://www.thenewx.org/forum/showthread.php?t=30646&highlight=steering+wheel+controls
Thanks for looking.
