The battery warning light is normally an indication that the battery is not being charged. In most cases, it means that the alternator is not generating electrical power. Driving a car in this condition does not cause any danger but all electrical power is being supplied by the battery rather than the engine. When the battery discharges, the car will simply stop running. Although it is safe to continue for a short time, it's important to get the car looked at and repaired.
