try some of these..http://cgi.ebay.co.uk/PHILIPS-H7-MOTOVISION-HEADLIGHT-BULBS-BUELL-BIKES_W0QQitemZ120394459137QQcmdZViewItemQQptZUK_Motorcycle_Parts?hash=item1c0811a801
The headlights on me Ulyssessessess are pants....so couldnt run to a HID kit but got the kids to buy a pair of these for me Burfday....
Having tested them for a week, i gotta say they get a big
from me...they claim a 10 to 20m beam increase...i'd say 10m on the Buell lights but thats 30 feetish..how much more do you need on dip, and on main the further a 55w beam goes it just dissipates.The new light emitted is a whiter light and does not get sucked up by the tarmac and does have an
range tint at the bottom of the lens which matches me bike air box cover... 
So if your confused about which bulb to try as i was, these are excellent...
