last night when i turned on my lights i had no lights in the speedometer. Fun driving home when you can not see how fast you are going. The head lights etc all work and the light on the original radio does also. All the fuses are good. could it be the bulbs went bad or something else before i dive into the wiring.

Or clean the crusty stuff off the back ofspedometer and make sure the bulbs are getting a good ground.
