Thanks for the replies, my bulbs came in the post and I fitted them following the thread on the R32 forum which was mentioned above. Took me about 15mins to do the first side as I did a dummy fitment run with the old bulb so I knew how to fit the new one and the other side took 10 mins.Not difficult at all.
The Osram bulbs are pretty good but they didn't blow me away as I expected them too but at least I don't have a pink one now!
Cheers
Sam
