Product Details : Key features: 1. YDM uses super-capacitor as energy-storing parts, which can be used more than 100, 000 cycles repeatedly and can meet needs environmentally. 2. Round design creates good appearance while relieving the impaction from traffic load so as to be durable 3. Two reinforced veins are designed inside to strengthen compression resistance. 4. Shell adopts one-off molding, greatly improving its Compression resistance. Solar panel, electronics and optics are fitted inside Material of shell:, dustproof and unbreakable up to International Standard IP68. 5. Two screw holes are designed on both sides so as to be fitted firmly in road section with high requirement of stability.
