The problem is that these projectors are Halogen Projectors which are made for Halogen bulbs and not HID, these aren't HID Projectors, so if you wish to use HID in those, then it's useless, but if you're willing to use Halogen Bulbs in it, then it's fine
Oh and a bit of advice, get a used pair of headlamps and retrofit in those instead of ruining the original ones
