You may choose your custom reflective sign depending on the visibility desired. Where engineer-grade reflective signs can be seen from approximately 500 feet away, high-intensity reflective signs can be seen from 1000 feet away, and diamond-grade from 1500 feet.
Engineer-grade reflective signs are the most pocket-friendly out of the three and are suitable for parking lots, private drives, and other low-traffic areas. High-intensity reflective signs are three times more reflective than engineer-grade and cost a little more. They are best for regular road and traffic signs. Diamond-grade reflective signs are by far the most reflective, three times more than their high-intensity counterparts and consequently, are the most expensive. Due to high reflectivity, they are best suited for crucial intersections, construction zones, highways, and other high-traffic areas.
Disappointed for the Second Time
I ordered this sign with a fleur-de-lis at the top. The one I received, after paying extra for quick shipping, did NOT have the fleur-de-lis. (Being in Louisiana, the fleur-de-lis was a major reason for this purchase.) Furthermore, my account indicates that I didn't order it that way, when I know that I did! There was no e-mail confirmation for the order, so I can't look at that. This is the 2nd time I have ordered from this site, and 2nd time that I have been disappointed. Update: They were quick to send out a replacement at no cost!
