We have been in our 3970 for about three months. I have still been learning. Tonight, I was doing a modification in the front closet and noticed two lights in the shelves. HOWEVER, I could not find where to turn them on. I assumed they would be with the light switch for the closet. But that is one of the lights that has the built in switch. I also thought they might be burnt out, but when I removed them I don't think they are.
SO, Who knows where these lights turn on from? Tommorrow I will test the bulbs in another light fixture to see if the bulbs are good.
