Here in the USA, we don't have the Bi-HID lights on the D2's, but my D3 had that feature, and it just flipped a small panel in the projector lamp.
But, as noted here, the "high beam" was still an halogen 55 watt bulb. (Easy upgrade to a higher watt bulb if you want, or going to a "silver star" or similar light, whatever they might call it in your neck of the woods.
