It ensures from all the dangers of a traffic diversion and is in itself a complete, independent signage in areas where projects take place. The light that “runs” in a wave-style from a lamp to another lamp, in a perfectly programmed time, gives a clear warning to the passing drivers, ensuring the avoidance of accidents. This unit consists of 10 Φ200 lamps, placed on plastic zebras of a 125cm height and rubber bases. Inside of it, there is a specially made, metal electronic system that controls the operation of the directional unit together with a battery 12V/180Ah. The different cable lengths that connect the lamps allow it to be placed in a length of 100m.
