These are simply the brightest, most conspicuous signs we offer.
• In the daytime they are fluorescent. Designed by 3M to be especially conspicuous at dawn and at dusk, this is the same material used for school crossing signs.
• At night, signs are Diamond Grade reflective. This grade of reflectivity offers superior reflective angularity and extradinary reflectance.
• All signs are 3M authorized and carry a 12 year warranty.
