'07 Radio Volume Control Lights

This seems like a silly question, but I have to ask...on the 2007 Suburban are the steering wheel volume control buttons for the radio supposed to have some sort of light on them?   Just wondering as every other steering wheel control is lit up. 

Not a Burb  but mine do not.

No lights on either of my vehicles

Great question, I thought the same thing.  They are designed that way.  I guess you probably would not be able to see them anyway since they are set back further than the rest of the controls. .
