Tran***rent spherical glass particle, used to provide night visibility for road markings by reflecting the incident headlight beams of a vehicle towards the driver.&©|160;
Reflective glass beads are among the most economical means to create safer driving conditions. Only road markings that contain glass beads are night-visible. No beads - no visibility at night. When a car's headline beam shines on a striping which integrates glass beads, the striping seems to light up and gets much better visible at night. This effect is called retro-reflection.&©|160;
Reflecting glass beads play a crucial role in maintaining visibility of motorist for driving under dim light or bad weather.&©|160;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.
