Traffic lights, also known as traffic lights, are one of the most important tools for maintaining traffic order every day in big cities. But perhaps the existing traffic lights have many flaws, or the future traffic lights are beautiful, the designers have redesigned the traffic lights again and again. Designed by designer Gisung Han, Hwanju Jeon & Jaemin Lee, this new solar traffic light is designed to maintain order on the sidewalk. 
The designer brought together two unrelated things, "trees" and "traffic lights," called traffic lights hanging on the trees. “Big tree traffic lights†are mainly composed of big trees, LED signal lights and solar panels. LED signal lights are directly installed on the trunk to indicate traffic signals. The red and green signals are controlled by wireless devices, while the solar panels are complete. The device is powered.
From the introduction of the design drawing, the starting point of this traffic light is for a better and more ecological urban landscape, easy to install, easy to identify, can be directly installed on any big tree, without the need to set up a separate cement pole Or irons, not only achieve the purpose of cost savings, but also reflect energy conservation and environmental protection, very suitable for urban and rural traffic construction. But this requires that each intersection must be planted with trees that have grown, or there are restrictions.
