    Just checking, for these, do i need the D1S Bulbs? how does it work for the full beams? Is it a H7 or another HID Bulb because thats what some of the configuration sites are saying but im sure they are both HID bulbs.

    It's only one bulb.

    A bi-xenon is a projector, on dipped beam it is effectively half open, full beam opens the projector fully. Allowing it to just use one bulb.
