Strange Dashboard Lighting Problem
 

2007 Camry LE. 4 cyl.

Has anyone heard of a problem like this before?

My dashboard lights (including speedometer, radio, etc) do not turn on when i turn on my headlights.

But if i turn off my headlights, all my dashboard lights turn on.

This just started happening over this last weekend.

Is there some setting i could have accidentily hit?

Any suggestions would be greatly appreciated!

Thanks!
