If I remember correctly from when I had a Mk V, both dipped and full beam are H7s. I changed the original dipped beam to Philips XtremePower bulbs (+80%) which were one of the best around at the time (5 yrs ago!) and they were much brighter and whiter with no glare. They outlasted my Mk V of 3 years and then lasted for another year and a half in my Mk VI (yes - I changed them over!!). When they eventually went, I replaced them with Osram Nightbreaker plus bulbs (+90%) which are slightly brighter again and still going strong after a year and a half (of heavy use).
I see there's now a new Nightbreaker - Unlimited which is supposedly even brighter but I have no experience of its longevity.
