Indicates a problem with the electrical charging system. Can be a bad battery, alternator, loose alternator drive belt, corroded battery connections, or ground connections. Normally this would indicate a problem with the alternator but not always. Most auto parts stores will check the system free of charge, if you buy the repair parts from them, which would only be appropriate.
