chances are if you don' t need headlights or air conditioning or other high current using accessories , you would never know that the alternator was in the process of failing! The time you will find out is when it is 10 below zero and you wear down the battery by cranking the starter , then put the fan on high for heat , and then drive in the dark u will face various problms u will face problm starting engine u will have dim headlights ac n blower will not be that efficient..

Why does your battery light keep coming on and off?
I assume you're speaking of a "low battery" light on a car...if so, it's because either a) your battery is failing, or b) your alternator is failing, and not recharging the battery. Check the belt that runs the alternator, make sure it's fairly taut. It's also easy to check a battery, most any auto parts store will do it for nothing.
