Cubarica, Check down in the Vendor's section for MR Works. They have done several headlight mods and needless to say, they are Amazing. Look through some of their threads and see what kind of ideas you come up with, they can do alot! Or look for
Marco@MRWorks on the forum.
Also look for member
2theextreme who also has a MR Blue Z and had his lights done by them. They look awesome to say the least. If I remember correctly, he did the exact paint scheme your talking about with black/color matched rings. So ask him about his lights!
