Instrument cluster Lights no worky on 65 Cuda

If thew turn and other indicater bulbs work, chissis ground is good. Lack of illumination may be simply bad bulbs. There are only 3 or 4 for illumination and they have a lot more hours on them than those other 4 bulbs. I choose to replace every bulb at once with sylvania 2825. Its a slightly brighter long life bulb. Available everywhere at approx 5 bucks per pair. Happy moparing
