2007 Interior Courtesy Lights

My wife drives the Av more than me so I'm not sure if she may have turned something of on accident but the last time I got in her to drive to work the interior courtesy lights did not com on, the worked fine the time before that for me. Lights do turn on manually.....
Is there a fuse associated with the courtesy lamps or a switch to press?

Switch on the upper portion of the rheostat control...says "Dome Off"....maybe hit it by mistake??
