Okay, another dumb question from me. As I've been fiddling with my '78 CB550 I've noticed that when I turn the ignition switch on, the headlight is always on. I can't seem to find a switch to turn it off. I have looked at this bike many times but have found no switch. I still haven't bought a manual for it, money's tight right now, but I will soon get one. So somebody tell me where the on/off switch is if there is one! Thanks
