Product Description

The 3M 7100138239 is a Diamond Grade Conspicuity Marking strip in the 983-71 ES series, designed to deliver high-visibility reflective performance on school buses and emergency vehicles. The strip measures 2 inches wide by 12 inches long and features a prismatic lens construction that returns light directly toward the source for superior nighttime and low-visibility detection. A pressure-sensitive adhesive backing with a clear poly liner allows for clean, repositionable application during installation.

This conspicuity marking is used on the side and rear perimeter of school buses, as well as on emergency exit doors, to meet visibility and detection requirements. The yellow color designation suits side-perimeter and emergency exit marking applications. Fleet operators, school district maintenance crews, and vehicle body shops typically install this product during new vehicle outfitting or compliance-driven retrofits.
