Dimming of Console

I have a 1999 323is and was wondering if the console dimming and returning to normal during the day without the lights on be about. Any one know could this be a battery or other electrical issue?

The console is designed to dim when the headlights are put on. Working on the principle that at night you do not need them lit up so bright to see them.
