The article above says you can change TF dipped beam from RHD to LHD by simply moving a lever, I didn't know this and presume others don't so have a look if you intend going abroad
Yep , I've used this when I take the TF to France . It's easy to do , you just need a long thin screw driver or similar to reach the lever that sits behind the head light reflector .
