Phew. Just finished reading this entire thread. (minus a bit of skimming over the essay post arguments)
So I think I've been convinced to grab the Osram 65W for low beams and HIR for Hi Beams. Hopefully candlepower ships internationally...
One question: (this may be silly, but I know nothing about auto lighting) would buying these bulbs be appropriate for my AUDM Liberty 2.5i, ie. there aren't any major differences that would prevent them from working? I haven't had a chance to check what bulbs it uses since I'm at work but will check the user manual at home this evening.
