ABSTRACT:
The invention relates to a control device for vehicular street traffic, including a signal disc which consumes very little energy. This signal disc is provided with signal webs separated by deep grooves and with a diffusely reflecting color coating. Pivotal slats are disposed in a frame in front of the signal disc. If the signal disc is displaced with respect to the frame, the slats are pivoted upwardly and push themselves completely into grooves. The signal disc is therefore visible at any observation angle. At dusk or at night, the signals may be given by suitably disposed, dot-shaped, colored light sources in the form of light emitting diodes.
