Pick the larger 17x22 sheet (#10228), which (when cut in half) is good for two headlights and the parking lights, too. I forgot to tell you that I covered my plastic parking lights, too, because a stone shattering it would also be a headache because you can't easily get a replacement front lens for these.

Griot's Garage is an overprice source, but the stuff is good. And I don't believe that the "pre-cut to fit" offerings at other companies will fit euroheadlights because they're probably patterned after the plastic USA headlights, and our euro's are probably a little different. This stuff is of large sheets that you cut yourself to fit (and there's enough left over for the parking lights, as I wrote above).
