I just bought a RS2 LHD in the UK
http://forum.rs246.com/viewtopic.php?f=22&t=98909 and understand it still has its original LHD headlight. From searching the internet and this forum I understand it is possible to switch the light between use on RHD roads and LHD roads. As I am driving my car home to the Netherlands at some point I will have to switch this. On the internet reference is made to a lever on the headlights to switch between RHD and LHD.
Is there someone on here that could clarify a bit more if possible with a picture of the lever? Is this something that is easily done (for instance on the Eurotunnel train

)
Many thanks in advance.
