No need to reply to this thread this is just a thread for people to see when they search for this because it seems like a common problem in the first model F4i.

Today my headlights failed and I searched this forum and other forums and I found out the problem. People were saying there was a wire loose within the starter assembly (lights go out when you press starter). Well anyways I went into my garage and it turns out my start button wasn't fully depressed causing the headlights to stay off, I had to pull it out about half a millimeter. So if you have this problem where both of your lights dont work or go on and off, the easiest solution before anything is gently try to pull your start button outward.

Any suggestions on a cbr900rr? only the hi beam comes on. I replaced the bulbs and the low beam came on but then went out again??? I checked the volts on both hi and low beams, checked both start button and light switch and nothin seems odd. Please help
