Junk, vintage! This is a set of 5 vintage bicycle W headlights. They appear to be unused, but due to long-term storage in a cardboard box, there is rust, dirt, scratches, clouding, and discoloration. I checked and there don't seem to be any cracks. Please judge from the photos, and refrain from purchasing if you are concerned. Please purchase only if you understand. Recommended only for those who appreciate the aging of the product as part of its character. Note: Mounting screws and wiring are not included. The light case is made of metal. There doesn't appear to be any noticeable rust, but some people may still perceive rust.
