Mikey, try here.
http://www.jpcycles.com/Or, one of these bulbs. If ya get 1 get 2 so they match.
The spotlights are GE H7616 they only use 36.5 watts and put out 70000 CP. Lights up the road very well. If you Google GE H7616 a pretty fair sized list comes up where they are available with prices. Back when I got mine I know I paid way tooooooooo much for them. At Bike Week that one time we went to eat on the Lake, they were in your rear view mirrors most of the time. Probably don't remember but if ya do, then ya know what I'm talking about.
I think, butt dyno here, that they are brighter than my old 50 Watt ones.
Also, I have to give credit to Highbinder for the information.
