Just as a note. Our 2011 RR has a little lever to allow us to drive on the other side of the road we have the Zenon or HID or whatever they are called. The lever in our case (LHD car) doesnt actually change them to to RHD lights it justs removes the "kick up" so essentially a flat beam, which maybe what they are in your case too.
Now Halogen I was under the impression that the beam pattern is done in the glass lens pattern, But I do know that
@Datatek has a little trick to get his P38 with Halogen through the test in france but I dont know what it is. As I have tagged him he may enlighten us
