    Benefits of Bright Signage

    • An icon of two arrows, one pointing towards and one pointing away from a street sign.
      Maximize reflected light.

      3M™ Diamond Grade™ DG3 Reflective Sheeting meets ASTM D4956, delivering more light than Types IV and Type IX sheeting products.2

    • An icon of dotted lines between a car and a street sign.
      Help make signs more visible.

      As headlights evolve to direct more light towards the road, less light is being delivered to signage. Bright signage helps prevent drivers missing important messages.

    • An icon of a shield beside a road.
      Help improve road safety.

      Type XI sign sheeting can help reduce the number of crashes over time by 25-42%.1

    • An icon of curved, sonar-like lines coming off the front of a car.
      Help improve machine readability.

      Many new technologies around assisted-driving are designed based on Type XI sheeting as it offers the best balance for all road users.2

    • An icon of an exclamation of a car beside a street sign.
      Command driver attention.

      Fluorescence commands the attention of drivers – day and night – and is particularly effective in low-light conditions.

    • An icon of a road sign indicating a curve in the road.
      Warn of hidden hazards.

      Fluorescent signage is particularly effective where roadway geometry or obstructions hide hazards for which the sign is providing warning.3

    • An icon depicting a distance of 53 metres between a car and a road sign.
      Give information sooner.

      Drivers detect fluorescent signs an average of 53 m sooner than their non-fluorescent counterparts.4
