Thursday night as I was on the way home from work, I stopped for gas about 6 miles from home. When I cranked the bike, my headlight did not work. All the other lights worked. I called my wife, turned the flashers on and followed her back home. Today, I removed the sealed beam (the plug was tight) checked the bulb and it had continuity. I then cranked the bike and I had voltage in the plug. I plugged the light back in and it worked. Anyone have any ideas? I don't need the light to go out when I am not in as safe a place as I was the other night.
