I've many, many kilometers in France on my RT12 and all I do is unplug the LH bulb and dip the headlight with the heavy load lever, works a treat.
However, a caveat... On my last trip in Switzerland, mate in front asked why I was riding in stealth mode (cue confused look from me) he said I have no lights on cept for the side lights which he said made me almost invisable in his mirrors compared to the other two guys I rode with.
Of course when I unplug my LH bulb the warning pops up (which I ignore) The RH bulb had popped on the road and I didn't know.
So 10 mins later side panel off and spare bulb fitted and all back together and off we go.
