Underwater reflective element for road marking
Underwater reflective element(ceramic glass beads) is mainly for wet night condition, underwater reflectance over 5cd, reasonable optical design provides superior retroreflectivity for road marking line, element combined by a core bead and hundreds of non-transparent high refractive index micron beads.
