Reflective devices are tools designed to enhance visibility and safety by reflecting light. Common examples include reflective vests, road signs, and bicycle reflectors. These devices work by using materials that bounce back light, making them visible in low-light conditions, such as at night or during fog. These devices are widely used in various settings, including construction sites, emergency vehicles, and outdoor sports. By increasing visibility, reflective devices help prevent accidents and improve safety for both individuals and drivers. Their effectiveness relies on the quality of the reflective material and its placement in high-traffic areas.
