Retro-reflective Sheet
Retroreflection is light source reflected by the same path in which it entered. Road signs using retroreflective sheets thus leap out at the driver at night when light is directed at them, aiding in traffic safety and order. “Bright safety and confidence, in all weather and 24 hours a day.” Progress must continue in technology to ensure safety, even if it will prevent just one more accident. Reflectors for aerial displays which also use retroreflection technology are expected to enable advances in signage of all types.
