Hi! Entry for this week is about Modern Invention. My friend and I had decided that we choose Hour Glass LED Traffic Light as the topic.
It is the time we were re-think the traffic light? Traffic control signal that date back to the 1860 and have involved very little since computers took over American traffic light in the 1950 ( at least the universal signally ) If you were you, to the whole driving think traditional include a red light for stop, a yellow light for yield, A green light for go.
Nowadays, people can use the sand glass concept for the traffic light using the LED system. With the hourglass traffic light, drivers will stop their cars at a red hourglass and wait for the digitized " sand " to empty and the hourglass to flip to green. Between a green and red hourglass will be a yellow countdown hourglass depicting the sand along with a 3-2-1 countdown number to better inform drivers of the time they have before the light turns red.

The conclusion is, modern invention nowadays is very useful to people. If this invention is often use to our country, country will more advance.
