The knobs look good during the day, but they do not emit any light through the "lenses" when interior illumination is turned on. Had no way to see any settings after dark. Also, the center Heat/cold knob does not have a limiter when this new knob was applied; I could spin the knob around entirely. Thought the limiter was broken, but it worked again when I reinstalled the factory knobs. Would be a nice touch for a show car, but I found them useless whenever I drove at night.
