There should be a ton of threads in the appropriate places dealing with HID's and projectors. This is kind of the wrong thread to be talking about headlights, but welcome to the forum. There's a ton of information and know how here on this site. Up above you will see the search button right next to my posts, type in hid projectors it will bring up a lot of info. Sounds like you blew a fuse, burnt out your bulb, fried your ballast, or just indeed need a relay harness to supply power from a direct 12volt source.
