Thanks for that info ainarssems, do you know anyone that's fitted these and seen good results over standard? They're not much more expensive than a pair of supposed brighter halogen bulbs so I'd consider trying them if anyone else has benefitted from installing them?

Yes me , Mike and couple of others. I used them with good results on PF S8 and C5 A6. Not so good on Freelander in H4 dual beam bulbs. There is a thread somewhere on the forum. Only problem was water getting in one of the ballasts so I have resealed all of them.
