anyone know where to find the micro bulbs that go in the factory Delphi cd stereo in my 05 silverado? The dealer said I'd have to buy a new stereo,which is stupid to replace a stereo because it has a couple lites out. I checked with my local parts stores,but they can't get them. the bulbs are about the size of a b,b, or smaller and have a plastic base you twist in 1/4 turn.
