One of the problems to be solved here is to allow the driver to see the traffic lights in front of him and prepare for this morning. Korean designers have designed a "Signal License Plate" that may solve this problem. This is equivalent to an intelligent license plate frame with an LED indicator bar embedded in it. It can receive the traffic light in front and display the signal synchronously to be seen by the following vehicle. If the front is red, then the LED on the license plate will also be displayed in red; if it is already green, or has already entered the yellow flashing state, then this LED will also change state.
Personally think that this design is very good, it seems very simple, but it is very practical, if it really has to be implemented first of all, there is a lot of design on the transformation of the existing license plate, and to get the traffic light signal information is another problem, not Know if these problems can be solved one by one, and look forward to the launch of this traffic light reminder.
