nice find..
yes euro foglights are H11.

my take from details on their page is that it's more for looks than practicality. I mean, you wouldnt drive around with your high beams on unless they were really dim.

" Suitable applications:

* Fog Light Lamps
* Driving Lamps
* Turn High Beam into City Light "

i think you'll find you wont have any power issues unless you leave your foggies on with the engine off for an extended period of time, which you just generally dont do anyway.
