Sorry, the group buy finished. The lenses bought for that came from a German supplier who advertises on Ebay, although you will also need to order some seperate bulbs.
If you put up on the group buy thread that was running for these I'm sure you'll get a bunch of people interested, as there have been lot's that have been looking for them.
I bought some fantastic bulbs off of a great lady on ebay slight blue tinge headlamp bulbs and then i emailed her to ask if she had any brighter sidelight bulbs to go with the headlamp bulbs as they were so yellow :-s
I ended up buying LED sidelight bulbs that are quite no very blue at a grand cosst of £6.99 WELL WORTH IT :-D
