first thing to do before installing them is to look at the bottom of the headlight and you will see this sign...
next thing to do is to flick this switch over its just to the right of the projector...
it needs to be pushed out up to the top and then in again
they should now be set to RHD and will pass an M.O.T.
* a warning with doing this though, half of my side lights went out mid doing this so make sure you have spares to replace them with the type of bulb needed is called a 286 bulb just type that into ebay and you can pick up like 20 for a tenner, there are 5 bulbs in each halo ring
this is what i mean by sidelights will go out lol
