Trailers that are 80 wide or wider, or that are 30' long or longer need additional lights and reflectors. A trailer that is 80 wide or wider and has a Gross Vehicle Weight Rating (GVWR) over 10,000 lbs. requires conspicuity treatments. These treatments consist of strips of reflective tape or rows of individual reflectors that create an alternating pattern of red and white along the sides and rear of a trailer to make it easier to see.Our Reflectors may be used for many other applications to promote visibility and safety. Not recommended on unsealed wood or concrete. A thin layer of a clear primer may be used to promote bond on porous surfaces as it will penetrate the surface and eliminate water from wicking under the sticker adhesive.
