Una señal de carreteras perfeccionada caracterizada por que su superficie presenta la forma de múltiples pirámides truncadas que ofrecen, cada una de ellas, cinco facetas situadas en distintos planos, lo que hace posible que, en todo momento, exista una serie de estas en plano vertical con respecto al rayo de luz en movimiento proyectado sobre ellas, condición indispensable para que se produzca la reflexión, aparte de que, el paso del haz de unas facetas a otras, produce una sensación de centelleo.
