Guardian / Traffic light

Drivers and pedestrians on the crosswalk head towards different directions. Therefore, they see signals from different directions. This traffic light, using solar power as its main energy source and electric power as its supplement, gives signals using a four-sided LED panel. Drivers see the red light on their side of the panel while pedestrians see the green crossing signal. This also introduces a new signal method. The main traffic light makes a pair with a half-sized assistant and sends a laser beam to it. This noticeable laser beam will make drivers and pedestrians observe the stop line more willingly.
