Researching a lot on HID and the best retrofit would involve replacing the stock halogen projector with a projector with optics designed specifically for an HID bulb. I know from the posts throughout this forum that the stock halogen projectors seem to work well with retrofit kits. Has anyone taken the next step and changed the projector? What model and bulb was used? I know the premium/performance projector may not be a direct swap because of the adaptive light features. Thanks
