3i has spent two years developing the world's first low profile, wireless (inductively) powered, intelligent road marker.


iiilevel™ (pronounced eye-level) is manufactured from high-tech polycarbonates and uses energy efficient LED's. The iiilevel™ is inductively powered and has no direct wire connections! The cable is buried in the road and power is transferred via an air gap. Consequently, the system is quick and cost-effective to install and run, as well as highly durable even in the heaviest of traffic conditions.


iiilevel™ is powered by 3i Innovation power supplies which offer intelligence with a patented 2-way communications and diagnostic capability. Through the existing 3i power system, information can be sent wirelessly to control the output of each iiilevel™ light (flashing, sequencing and degrees of brightness) as well as receive data from each iiilevel™ (marker performance, road temperature and vehicle speed). The power supply itself can run up to 2km of 200 road markers from a single source, and can be powered by both mains and by a solar panel.
