It could be a couple things. First check the battery posts are clean and cables are snuggly connected. Then make sure the cables are in good condition. Worst case it's your alternator. To check your alternator just call your local parts store (kragen, autozone) to see if they test alternators. If they do pull it out and take it to them. If you're not able to do that yourself and don't know some one who can you'll have to take the car to the mechanic.
The light is telling you that there is a problem with the charging system. You are running off the battery and will eventually get stuck with a dead battery if you continue to drive that vehicle with the battery light on. Drive to your local auto parts store and they will test the charging system for you at no cost. You are probably in need of an alternator.
Follow the positive battery cable from the battery, it will lead you right to the starter.
Your battery is dead.
