Reach down and lift up on your e-brake pedal and it will go off. The cable may be loose and your pedal is sort of flopping around, tripping the switch to turn the light on. I've noticed that the sensor is very high up in the pedal reach, so even the slightest "engagement" of the e-brake and the light will turn on.
