Improvements introduced in the manufacture of reflective light reflectors, characterized in that said reflectors are made to have a layer of transparent small spheres and a reflector means, the spheres having a refractive index comprised between approximately 1.70 and 1.90. Which produces a strong brightness, the small transparent balls being attached to said reflector means so as to produce reflex reflection.
