Dashboard Lights are Flashing

Why are my dashboard lights flashing? Also when this is happening my speedometer and rpm gauge flicker. Is it a computer or electrical problem?

If you mean the lights are pulsing in intensity the trouble is most likely due to a problem in the alternator. There may be some bad diodes inside it. You can have the output checked out real easily at a shop. The battery condition should be checked also.

Do you really expect an answer after offering such little information? What is the year, make, and model of the vehicle in question?
