How to make a passer-by to cross the street safely at night?
By infrared ray, the light will sensor where the passers-by are, and will follow the passers-by from one side of the road to another side. On one hand, the passers-by can see the road, and on the other hand, the driver can see the passers-by in front of the car. Although the driver doesn’t notice the passers-by, the driver can see the light get through the road.
