Im also a little confused as to why the seller seems to think you need different headlamp units for driving on the other side of the road, the xenon units have built in shutters for adjusting from left to right hand drive dispersal patterns so you don't even need stick on head lamp converters
LHD and RHD headlights aren't the same. They have different part numbers on etka
I wonder if thats down to the main beam dispersal pattern being set up differently?? otherwise it would seem pointless producing different units for LHD and RHD when they can simply be setup differently. Im not saying your wrong by the way just find it odd.
And think Apollo is probably right, re-looking at the picture the projector seems to be diverted in one direction not straight ahead.
