"beam benders" are available for using RHD cars in LHD countries, and are reasonably priced.
They are self adhesive and you can 'stick' them over the original headlight lenses to defract the beam to the opposite side. They work effectively and they are totally road legal.
Thanks for the beam bender reply, but that doesn't help.........I was hoping for a permanent alteration to the lights to make the vehicle LEGAL in France i.e french registered.
For a permanent solution there is an english company in spain who do the headlights you are referring to. You can contact them here -
