LED Lane Indicator is the element of safety needed in unlighted tunnels. In tunnels with lighthing equipment, the light intensity is high and as a consequence the operating expenses is also high.
This can be reduced by using LED Lan Indicator. What is more, LED Lane Indicator indicates the road side also to vehicles entering unlighted tunnels without their own headlights turned on.
Electricity is supplied either via the local power supplier, or in areas without electricity, it is supplied by solar station.
Energy consumption being extremely low, a tunnel of 300 meters would require no more than the equivalent of a mere 10 watt bulb.
