Dan,
Im at work as I type this so I can't verify this for 100%, but I am about 99.5% sure that my 2002 FC550 has a lighting coil and all the wiring for it, just not used. All I think I would need to do is add a rectifier(not on bike) if I also wanted to go with a battery setup, or capacitor w/o a battery setup. From what I understand, either of the two mentioned options would only be needed if I was not concerned about dimming of the light under less than normal RPM's or when the bike is not running at all. Of course the capacitor would not allow the bikes lighting to run for any extended length of time with the bike not running. Hope this helps.
Regards,
