The 4 pack reflective conspicuity strips are designed to conform to applicable US FMVSS108 and Canadian CMVSS safety standards for reflective tape. Ideal for outfitting any trailer, truck or large vehicle. The easy-to-use conspicuity tape is hermetically sealed and pliable and features industrial-strength adhesive for quickly mounting on flat or curved surfaces. The professional grade reflective material has higher visibility at long range and tougher durability than conventional conspicuity reflectors. Each red/white pattern measures 11" red and 7" white.
