I just got my scorpion moped running, and on the first ride the head light pulsed on (not very brightly), and then off, and has not worked since. Clearly the bulb was ok for it to work in the first place right? Could this be due to old wiring? Burnt out bulb? I would think it is wired up correctly since it initially turned on, but looking for some insight. I don't think the brake light worked at all. I can post a video if needed
