These are extremely bright commercial grade tapes. The brightness and the contrast between the two colors is what makes this tape stand out day and night. One of the absolute highest quality DOT Tapes on the market. Not a cheap Chinese tape. This is a premium American made reflective film. Made in the USA. Easy to apply. Simply peel the backing off and apply to a clean surface. Then apply pressure using a squeegee or soft cloth. Oralite (Formerly Reflexite) prismatic tapes are made in a patented single layer design thus eliminating problems that arise from delamination. Oralite tapes DO NOT come apart like other brands. 2" DOT tapes are certified for trucks and tractor-trailer applications.
