Light bulb for the clock and defrost buttons

Any one know how to change the light bulbs for the clock and defrost buttons?
I got my stereo system out and replug everything , but the backlight went out for the clock and defrost buttons.........

I saw many cases like this, but I don't know how to change the bulbs!

The bulb is in a screw in type plug in the rear of the clock. Very easy to do. Just get the bulb at the dealer..
