Try the night lights. Not exactly sure on the Newport, but I think there's a switch upstairs somewhere and one on the end of the island. When on, small lights in the wall near the floor will light up. Usually one in bathroom, one in bedroom, one or two on the steps and one on each end (narrow end) of the island.
If your lights come on but not the ones on the island, I think Dan is on the right track here.
If your lights come on but there are no lights installed in the ends of the island - could be a production miss. In that case, you'd want to contact customer service (877-262-8032) to inquire if it was a miss or not. It's entirely possible that the night light feature was in its infancy and was not ready at the time your unit was produced - yet perhaps the circuit had been run.
Thanks for the info, do have three of the small lights, two at the stairway, one in he bathroom, none in the bedroom or kitchen. The switch for these is at the main switch panel, there is a switch in the bedroom so far haven't figured out what it controls. Will be contacting customer service.
