The drivers side of my radio does not light up. Is this a serviceable item (replace a bulb), or is it all inside the radio unit? This is the factory AM/FM/CD/cass. with the infinity sound system.
Its just a minor annoyance, but I might as well address it when I tear the dash apart for dash mounted gauges. The answer shold be obviuos when I dig in, but a little knowledge ahead of time might save me a trip to the parts store

 

most likely the lighting is an LED mounted internally in the radio head unit.
