Exact same thing happened to me last weekend. At first I did not realize the lights were blown out, since it happened in the daylight. I thought something was wrong with the display. Then on Monday, I thought I would look things over and noticed all 4 headlights and the brake/taillight were shot. I assumed it must be the Voltage Regulator. I had that replaced on Wednesday as well as all of the lights. The display must have a built in safety feature that prevents it from gettting burned up by too many volts so it is still working. We finally got some decent snow and some good riding yesterday and all seems well 175 miles later.
