Any chance you could find a link to the exact one you used?
I think this is the one- there are several sellers on eBay I used "the alphamoto" but they no longer are selling it. There are a few to choose from though...
I just took out the bulb they supply and put it the factory fz6r bulb- way brighter
Hope this helps...
