I have a 2004 Tomos Sprint, I noticed the other night that when I turn my moped on the tail light will come on but it shouldn't do this unless I turn the lights on. If I turn the lights on the brake light comes on and if I use the brakes nothing changes. I did take it in a while ago to get the front head light checked but because the low beam wire whould shake lose. I don't know if this is related or exactly when the rear light started messing up. Anyone have a idea whats going on ?
