General description

A pair of mobile traffic lights is used at road construction sites and other road sections when a one-way traffic arrangement is necessary.

Both traffic lights operate independently, with a battery power supply. For lower energy consumption, traffic light heads are assembled from LED diodes. The traffic lights are mutually synchronized via wireless radio-wave communication.

The traffic light operation adjusts automatically according to the traffic density. A microwave radar detector is used as a built-in traffic sensor.

The function parameters may be adjusted through a keyboard and built-in LED display on the spot directly, depending on given circumstances.
