It's called a reflection. Chrome does that.
not sure how to take your reply, cocky or straight forward, but I am commenting on the appearence that the gentleman selling them says they need some work and they looked rough in the photos. I do appreciate the lesson in how chrome is a reflective material. For your information, did you ever happen to see what chrome looks like when cleaned with an abrasive substance. Kind of like swirls in paint! or kind of like those wheel pics.
