The best way to tell if you have lens (and bulbs) made for the US is on the front glass it will say DOT, which is the dept of transportation approval for the beam defraction configuration (where the light goes and more importantly where it doesn't go). If you drive a lot of rural back roads the best configuration is to buy one for US and one for a right hand drive (like Australia). Stick the aussie lens in the driver side. (this is not a thing to do for driving with on coming traffic)

Jimeg are your HID lights a full kit or are they H4 HID bulbs in a 7" lens? you might what to check to see that the bulbs are seated correctly in the lens.

On my BDR the adjustment screw was backing into the lens bucket and limited adjustment. Make sure the back side of the adjustment is free.
