The halogen headlamps just seemed to have the normal up / down and side to side adjustment.
I'm not aware of any way to change from RHD to LHD with this lamp. The Xenons might be a different matter, I just don't know.
I used to have a Renault 16 with standard fit Cibie headlamps. When you put the headlamp bulb into the reflector there were two positions that it could be fitted into; one for RHD and (by twisting it through 30 degrees or so) one for LHD. Ingenious! It's just a Pity I wrote it off though
