My parents got me the bi-xenon kit from vvme.com for Christmas. They accidentally ordered the wrong type of bulbs with the kit, as you know, new edges take 9007 bulbs, but they ordered H4 bulbs instead.

My question, are the ballasts and harness interchangeable, and do I need new bulbs? Or does the harness and the bulbs need to be changed, or possibly the whole kit?

 

from the impression I get from here half the time they do not have the correct wiring even if you get the correct kit.....
