I would check all grounds and measure the voltage output at the battery with the engine running. Voltage should be between 13.5 and 14.5. If not then the alternator, (regulator?) should be checked.

does it only happen when you are stopped at stop light (in gear) or does it happen when you are driving around (moving), and also do you have a big stereo?

Check your altn. belt and make sure it's tight.
