A bit crap aren't they? The ones on my father's A4 provide a way fuller beam. Mine seem to have a hole in the middle, or just not very good at all. Athe H7 Osrams Silver Star / Philips 50+ just as good replacements for the main beam as they are for the dipped? Considering getting them from powerbulbs.co.uk with a pair of matching side lights for the Xenons.
