Negative Positive
Title: Novel use
Review: I actually bought this red lens to convert a bright white bike headlight into a tail light for my wife. You can't really get super bright tail lights but this lens helped me sort of invent a new product that my wife uses when she rides at night and she loves it. The quality is very high, the plastic is tough, you can bend it more than in half and it doesn't crack. The finish and circularity are all top quality, too.
Is the review positive or negative?
