If you want the mini lights, plan on about $400 in parts, And all the body, paint labor, and paint costs. Probably over $1500.
Could you possibly use older Jetta lights, but use the Angel Eyes set-up? Maybe Corrado Angel Eyes since they are more square?
I'd love to see a headlight mod done. I like the BMW ones you show, but if you are into practicality and safety, maybe these would work?
