The Bosch ballast came out of an 03' bi xenon BMW 3 series. The projectors were sold. Whats left is the ballast and bulbs. The bulbs are Philips D2S. One of the bulbs had a tear in the return wire. Its been repaired and doesn't hurt output or life of the bulb. $300 shipped for everything. If you have the bi xenon projectors just wire it up with this and your set. You do need the 9006 socket. It won't come with this setup.
