basically make a light shield around the top of the 9006 bulb in place of the lo/hi 9007 bulb for a low beam (putting the shield there to create a cutoff like on projector HID's, put a high beam bulb up where the turn signal bulb is, and move the turn signal to the parking light bulbs. Then wire in the low and high beams so when high beams are on both low and high beams are on, not just high beams like stock.
This way one can have both low beams and high beam hid or just low beam hid with halogen highs, and have lows with a cutoff so as not to blind oncoming drivers.
Basically a sub $100 setup to make HID's more oncoming traffic friendly.
