The new class horse Appear
Traffic lights change
Just double measurement have become red
Pedestrians can cross over the road
But not quickly identify
I want to use the settings in the far infrared signal lights on,
When the pedestrian light turns red line,
Start of infrared radiation,
Let passers-by know already through.
