The function of the reflective vest is to form a very strong light reflection in the case of light exposure, which can stimulate the driver’s visual nerve, remind Bai to pay attention to pedestrians in front, and drive carefully to avoid accidents. Reflective vests are mainly suitable for police officers, road administrators, traffic directors, road maintenance personnel, motor and bicycle drivers, workers in low light, and other places where workers need to use light to warn. The main body of the reflective vest is made of mesh cloth or plain cloth, and the reflective material is a reflective lattice or high-brightness reflective cloth.
