It is manufactured in accordance with German specifications and the technical road safety conditions for flashing lamps. The bright arrowhead “right” or “left” appears at a distance greater 500m. This gives the drivers enough time to reduce speed and to prepare to change lane, when the arrow is used in worksite marking, while it also protects the motorway maintenance workers when placed on a slow-moving vehicle.

There is a built-in photocell to reduce the brightness during the night and to increase it during the day. The arrow is formed by a reflective membrane. It works with a 12V-170Ah battery.
