The reflective road pole anti-collision warning sticker is made by the high refractive index glass bead reflex principle, which is made by the advanced process of post-focusing treatment. It reflects far-reaching light back into the glow, providing good retroreflective optics both day and night. Especially at night, you can enjoy high visibility like the daytime. The use of such high-visibility reflective materials for reflective road poles, anti-collision and reflective warning stickers can be easily found by night drivers in remote locations or in the presence of light or scattered light. The appearance of reflective materials successfully solved the night driving problem of "seeing" and "being seen".
