after seeing quite a few stock E70s in my area with nice whiter angel eyes i called my local BMW and asked about different bulbs because mine are very dim and the ugly 90's stock colour.
the lady i spoke to at first didn't even know what angel eyes were so after i referred to them as rings she said they upgraded them to ones that are whiter.
haven't had extra money to go down and check if any of this is true but im hoping so because they looked very nice.
