The light is supposed to go out when the stator is generating power. Put a voltmeter on the battery with the bike off, take a reading. Start the bike and rev it up, does the voltage rise? If so, the stator is OK and probably the circuitry in the on/off switch is kerfluwy (danger-tech term).

Stator, rectifier/regulator, bad wire or connector possibly. Get you manual out and begin the troubleshooting steps.
