Graffic / traffic light system

Graffic
Graffic

Car drivers often can't see the traffic lights because they are blocked by some buses, which resulting in slow start or running the red light by mistake.In order to avoid the traffic lights being blocked by large vehicles,road signal lights are set on both sides of the road. When the driver's sight is blocked,drivers can easily see the signal light.When the vehicle is moving, the deceleration belt is pressed to convert its gravitational potential energy into kinetic energy, so as to supply power for the road signal light.
