“How did this big fan end up on the fast lane?†Many drivers who passed through the northwest semi-circular expressway yesterday were surprised to see a large, fan-like device. In reality, it's not a fan at all — it's a new warning system designed to improve road safety. Known as the “solar flash plum light,†this innovative device helps alert drivers to slow down when there are traffic stops or construction zones nearby. It can be seen from 200 meters away, even in the dark, giving drivers plenty of time to react and adjust their speed. The new “Solar Flashing Meihua Light†was first deployed on the northwest semi-circular highway on the 16th, assisting traffic police in monitoring trucks on the Minhang section. According to the police, the device is equipped with solar panels and an internal battery, allowing it to operate continuously for 24 hours. At night, its bright flashing lights serve as a clear warning to drivers, significantly improving visibility and safety. These smart devices not only protect officers during traffic enforcement but also help prevent accidents by keeping drivers alert and informed. This technology represents a major step forward in smart traffic management, combining renewable energy with real-time warning systems. As cities continue to grow and traffic volumes increase, such innovations will play a crucial role in ensuring safer roads for everyone. With its eco-friendly design and high effectiveness, the solar plum light could soon become a common sight on highways across the country.
