These rectangular self-adhesive reflectors are suitable for trailers, caravans or other vehicles. The reflector requires a flat, clean surface to ensure the self adhesive can bond correctly. Red reflectors are used to mark the rear side of a vehicle or trailer. It is an MOT requirement to have red reflectors on the rear of the vehicle and it is an important safety feature. The reflector is E-Approved which means it is road legal and suitable for use across Europe.
