Trace the wire coming from the righthand brake pads. You'll find that it is stretched very tight between two of the hydraulic brake lines which can vibrate independently. This fatigues the wire and can cause the conductors to break. The light didn't go out when you disconnected it because it needs continuity. I'm guessing that if you'd shorted the two leads inside the cable, the light would clear.
I cut one of the wire-tires, releasing the cable where it was stretched tight, just above the front fender, and I hope that this will prevent the problem for me in the future.
