Review on Enhance Nighttime Safety with B REFLECTIVE Éco Multi: 12 Retro Reflective Stickers Kit for Bikes, Strollers, Helmets, and More by Eddie Orrell

They work: highly visible reflective elements that are effective when hit by headlights. However, it is important to know that they should NOT be used as a safety feature on normal day trips, especially on children's bikes. They should only be used to supplement white, orange, red, etc. high visibility DOT reflective materials on other parts of the bike. #One less car
