I have 4 9004 hid kits just sitting around. As far as anyone knows, is it possible to fit this is a cbr f3, rewire the headlight, and get it working? Or at this point would it just be easier to keep all my ballast and get a h4 bulb?

 

No, you need an H4 bulb. Not sure if the ballast would actually transfer over from 9004 to H4. Do keep in mind, aim your headlight if you get bi-xenon, you'll most likely have to swap the pins around and then aim the housing, otherwise you'll **** some people off.
