I had stock non-hid bulbs and I bought hid headlights with ballast off of someone on this forum.

The ballast was from an audi I believe but now it has stopped working.

I need a new ballast and I have no idea which one to get. I cant get a BMW oem one because that requires slicing a wire.. I do not want to do that.

Can someone recommend me a kit that will work? Thank You.
