I believe that is the alternator light. If it stays on with the engine off, there may be a bad diode in the alt that is allowing power to pass back through the alt to ground. Have the alt tested. Most parts stores will do it for free. Ask them to make sure to pay special attention to the diodes.

Let me know what you find.
