dash lights

This is on a 2004 Suburban 1500. Are the little figures (signs) whatever they are called that show what position your head light switch is in supposed to illuminate at night? The windshield wiper signs are lit, but not the ones where the light switch is located on the dash? Can't remember if they ever worked or if a bulb is out??

Thanks

I just go the truck back from dealer and they replaced the dash cluster becuase the speedometer went out and not sure if they screwed something up or what??
