What's up fellas,

OK, My headlights work fine, Highbeams work fine and then I plug in my HID's and I get nothing at all. I know the HID's are fine becuase I took them out and plugged them into my Bro's car and they lit right up. I am clueless to what to do. Hook a brother up with some ideas! Is there another piece I need to buy since it is a newer car or what? I dunno
