Projectors. cool.
Anyway, You will need the following:
1) HID ballast (preferably a 35W). Try to get a waterproof one.
2) Wire harness (this wires directly.... plug and play.....connect to your low beams and to the HID ballast). wire harnesses usually include a relay. If not, walk away.
3) Pick an HID bulb, try 4300-5000K (anything less or more is worthless as far as lumens are concerned).
Try TRS (the retrofit source), customer service is A1, but a little more expensive. It's akin to contacting Crutchfield if you have limited knowledge of HIDs (radios and connections). You will pay more but its totally worth it.
Good luck
