Need socket for this light bulb - where to look

[sofasurferlinux]

I want to use this light bulb... Eiko 48012 A-3598H ...but I am not able to find a source for the socket to plug it into. It is supposedly used on motorcycles and snowmobiles.
Anyone know how to find something like this?

Never seen anything like that before. Did you notice that it is a 15w/15w bulb?
