 If you come from Europe, we recommend that you use the EN1423 (710-125um) or (850-180um). We have already certified by the European Union;
 If you are from Korea, we recommend that you use KSL2521 Type 1 (1). We have been certified by Korea;
 If you come from America Canada, we recommend that you use the AASHTO M247 TYPE 1; some other countries prefer to use BS6088 A or B.

1) Product Function:
   Improve the road marking line contrary reflection function. When driving at night, the lamp shines on the marking line with glass bead in it, the ray of lamp is reflected back parallely. So the driver can look at the road clearly and drive safely at night.
