I bought 3 sets of these, some for my kids and myself. They look great when riding at night and also give drivers a better view of you when riding at night. We have strict rules on night riding such as having a front lamp and back light, and these were a great addition to bicycles to add a bit more safety. The more people can see you the better. I had a police officer talk to me one night on a ride and he said he really liked the lights he could see them well from a good distance and thought it made the rims look cool. They are brighter than I thought they would be so I am happy about that. They are a great addition not only to keep you safer, but it looks cool too.
