I just received an Olszewski Sleeping Beauty Castle piece and was wondering about the lights.

Under the little tree in the rear, there are two small switches. One is for the two lamp posts and the other is for the red and blue castle lighting, correct???

The other thing I've noticed is that after about fifteen minutes, the lamppost lights go off, but the red and blue lights stay on longer. So far, they've not gone off at all. Do I have a defective piece or is this normal?
