Approved triangular red reflector, measuring 155 x 137 mm, specifically designed for rear installation on trailers. Thanks to its triangular shape and large reflective surface, this accessory greatly enhances trailer visibility in low light, fog or night conditions, helping reduce the risk of accidents. These devices do not produce light, but reflect it back to its source by combining reflection and, in some cases, refraction. It is essential for increasing trailer visibility to other drivers, especially in poor visibility conditions. This model includes two mounting holes, allowing for quick, safe and hassle-free installation on the rear of the trailer. These reflectors are available with or without screws, to suit different installation requirements. Made from high-quality PMMA (polymethyl metacrylate), this triangular reflector provides outstanding resistance to wear, harsh weather conditions and intensive road use. Its robust design ensures long life and minimum maintenance. With dimensions of 155 x 137 mm, it offers an ample reflective surface without being bulky or intrusive. This reflector is only suitable for use on the rear of the trailers.
