I was wondering if upper end models of the S80 have ambient lighting. I noticed on my S80 that the interior door handle bezzels have a slit in the plastic that appears to be a place for light to come through. Does anybody know if all S80's are prewired and just need a bulb plugged in? My windows are getting tinted Tuesday, and while the door panels are off, I'd like to have a bulb put in if that's all it takes.
