Does the interface light up on Bose cinemate gs2?

The Bose Cinemate GS II does not have an interface light.

The system relies on a small, rectangular remote control with buttons for power, volume, input selection, and other functions. There are no lights on the speakers or the subwoofer.

If you are looking for a Bose system with a lit interface, you might consider newer models like the SoundTouch 300 or the Solo 5 TV sound system.
