2. What is the core component technology?Durable, high-intensity Light Emitting Diodes (LEDs)
3. Why do these lights help drivers and pedestrians?They give bright, clear signals that stay visible even when paint fades or snow covers the road, so drivers can see crosswalks and curves better.
4. How do the lights know when to turn on and off?The lights use sensors that detect light, rain, or cars, so they turn on at night, during bad weather, or when a vehicle is near.
