Everything together will probably cost a bit over $300. This includes the HID kit + 2 Hella Lamps. ($135, price+shipping, I'm not a vendor, I have to pay for everything retail
You can of course source your own Hella lights, HID conversion kit and/or make your own wiring harness. I can supply the light bracket and the face plate.
You can source your own harness here or make you own.
