山路弯道牌 / Card for Mountain Curve


In view of the potential safety hazard when a car cornering on mountain road, an intelligent reminder card is designed expressly for mountain curve.
This product is powered by solar panels on the back, of which the LED display can show the curve radian and orientation directly. The severer the curve is, the smaller the angle of the red lights becomes, so that drivers can quickly identify the urgent degree of the curve and be aware of it.
