Although headlights can provide illumination, they are often large, inconvenient to install, and consume a lot of energy. Although reflective strips can reflect light under the illumination of headlights, they are ineffective without illumination, and the visual effect is limited, failing to provide sufficient visual warning. Therefore, it is necessary to design and develop a device that can improve the visibility of motor vehicles and non-motor vehicles at night and enhance driving safety. Utility Model Content
