Guardian / Bus license plate


The Guardian is a mobile traffic light warning device installed at the rear of the bus based on this problem. When the bus is running normally, the warning Lamp is closed showing bus routes and driving information. When the bus is temporarily stopped and the current infrared detector detects someone or vehicle passing by, the rear "warning light card" will quickly open to 90 degrees. The "warning light board" rear LCD screen will display the "pre-pedestrian" warning text and icon to remind the rear car to pay attention, and prompt the rear vehicle to slow down and stop waiting.
