European Switchgear On A Us Speed Twin

Ask me why I am doing this and I'll say "Dunno", but I think it's because when I took the headlamp out to replace the turn-signals I noticed all the gubbins are there for the Daytime Running Lights which appear to be on when the low beam is on, but because there is no button on the front of the left hand switch gear the lights are always on. My Multistrada had running lights or a low beam on but you could toggle between the two with the high beam only staying on in conjunction with the low beam as opposed to the DRL's.
My question to the group is this. Does anyone know if the European switchgear would enable the European functioning of the US headlight, or would it not function, or blow the whole thing into a gazillion pieces and start the chain of events leading to the end of the universe?
