At least one reflector includes a light diode for emitting light with the same color as the reflector. The color of the reflector on the front side of the helmet is different from that of the reflector on the rear side, preferably so that the front one reflects white light and the back one reflects red light. Reflectors can also be provided on the lateral sides, preferably so that they reflect yellow light. A means can also be provided for activating the light diodes when the helmet is placed on the head. |
