Glass beads for reflective coatings are a prior choice as per the customized results provided by them. The decision to use glass beads is based on the manner in which they reflect light. They function as small lenses in covers, rerouting light that arrives back into the source to increase luminance and intelligibility. Glass bead-containing reflective coatings are commonly used in highway safety programs, including security vests, traffic signs, and roadway markings.
