Anyone know where to buy these (apart from ariel that is!)

from ariel experience its a home brew casing they are just using the lenses from manufactures and are readily available...i was involved with mate who offered me to run a track day hire company for him with his atom and had some experience with them.....but if you contact a bloke at a company called vegatune.com speak to richard...tell haydn sent ya and he may be able to help.....he services and maintains atoms for blokes who track and race atoms.....nice guy..

Cheers for that.
I'll give him a call
