Transparent spherical glass particle, used to provide night visibility for road markings by reflecting the incident headlight beams of a vehicle towards the driver.
Reflecting glass beads play a crucial role in maintaining visibility of motorist for driving under dim light or bad weather. They are widely used in highway and airport runway and other pavement transportation systems such as zebra crossing in urban traffic road,cut off line,double amber line road marking etc as reflective materials.
