thanks for the quick help i would look my self but the bike is still in storage. :x winter sucks! :(
You need a H4 or 9003 bulb, they are pretty much the same thing
Yeah 9003 or H4 will work perfectly, theyare the same bulb.
There are also plenty of discussions about replacement bulbs if you are looking to upgrade to a "better" bulb.
