Good point....so scratch that idea....
Ahhh... DIMMER Sensor... that makes more sence. That I do have. Got two (at least) on my dash. But they aren't in the cluster. If it is that, it seems kinda out of place.
I have the dimmer switch as well, but have you ever noticed that as you drive, say through a tunnel or long underpass, that the lights inside (if on, ie the radio) will brighten up?
