It seems the display lights in my radio/CD player, and my heater control are becoming dimmer. Turning the dash control switch does not have an effect. I have replaced most of my dash lights with LEDS. Maybe the lights are dimmer in comparison??
Has anyone replace these radio-heater display lights? Can they be replaced?

 

I replaced some of the lights on my heater control panel. Several were burnt out. They just screw in, 1/4 turn ( 2 different sizes) . I got replacements at the pick and pull. The radio is tougher, IIRC. I think those lights are soldered to the faceplate.
