I am looking for an Aftermarket Headlight Bulb.. When I bought the bike it has these real sweet bright blue headlight bulbs. The other day one blew out. I called every motorcycle shop in my area and they dont have anything like it. I was wondering if anyone could help me find this bulb..

Here is what it says on the bulb.
Eiko H4 12V 60/55W 37R 252. I dont know what is what for Numbers..
The bulb also has a crazy blue tint on the bulb itself.. Thanks Joe
