Heating system lights

Hi...first am apologize for taking the picture from other user on this forum :)... Just wondered. is there on this heating controls any light bulbs that should be working? In the dark I see only one is working (and that is in the rear glass defrosting button), and other parts seems to have no bulbs? (or they are all dead :D ). Btw sorry for my english and thanks for the help

 
There should be 1 bulb in the middle to light it all up

Pull the 4 knobs off and carefully pop the front off. It's behind there
