Litronics have a lever inside the headlights with 2 settings. If I remember right the settings are marked 0 and T, and T is for tourist. In the UK they can switch the levers if they go to a LHD country and then not have to use the masking tape. But this lever does not convert a RHD litronic into a LHD litronic. What the lever does is to cut off part of the light beams so it is just like having the mask on the halogen lights. What you end up with is a RHD light with part of the beam missing, but legal in a LHD country.
