is it brake or abs?
is the float in the master cylinder stuck down?
there is a simple float in the master cylinder that acts as the fluid level sensor if its stuck it will cause this...can you check?
sorry im hear now..try unplugging the sensor on the side of the master see if that shuts the light off
and the master is 100 percent full? have you scanned for abs codes
its likley the level sensor has failed...is it a 2 wire plug?
jump the connector if the light goes out its the switch on the master
