Tail light conversion

I have a 2002 600, I got these flashing tail light turn signals and when i went to put them in, i found out that the socket connections is a 1157, and i have the 3157's. Is there a conversion kit available so I can use these cool turn signal bulbs? Otherwise, my friend has a Kawasaki ninja 900, and we put the bulbs in his bike and they worked. Is it possible to take the wiring harness from the ninja and rewire it to make it work on my F4i?

hmmmm....nobody has any suggestions?

got a link to the bulbs you are talking about?
