You could buy OEM HID headlights but they use a self leveling sensor on the suspension and they're expensive. ECS tuning sells them too.

The cheapest way is to buy an OEM quality projector headlight and put an aftermarket HID kit into it. You can't do it with a reflector beam like yours because the beam will be all messed up. Check out the Hella Dynabeam - Hella is an OEM manufacturer and they have sensors to turn the beam into turns. http://www.tmtuning.com/HOME/catalog/product_detail.php?default_product=1800 It has a projector lens so all you need to do is put a HID kit into it.
