    Back in around 1960, in the last few seconds of the red light before it changed to green, the yellow light came on, so drivers could shift their manual transmissions into gear and be ready to go. Also, near the end of the green light cycle, the yellow light then came on. The yellow and green were both on at the same time. Sometimes in small towns, the go light was blue. My Uncle Cap told us kids, there was a little man who lived inside the signal, who changed the lights and Santa brought him new light bulbs on Christmas

    The US traffic light system needs a MAJOR overhaul. I appreciate how the video mentioned lights works in tandem, and although they do at intersections, there are many lights along a street that do not. The outcome? Red light after red light after red light... We need smart traffic light systems that work in a network, going beyond what was described in the video. (Thanks for the info, by the way!)

    I disagree with the end of traffic lights. They never ever should've come out with self driver less cars in the first place. They don't even know what's going on.

    In my country, green means honk your horn as loud as you can and be an asshole, yellow is to go faster to reach the intersection before it turns red, and red means go if there are no enforcers to see you.

    Running a yellow light could be reduced if drivers were educated correctly on the road rules. You must stop on a yellow light if it is safe to do so. Anyone speeding up when they clearly could and should be braking scores themself a $1,000 fine.

    You forgot to mention some emergency vehicles (police, fire and ambulance) may also have a remote control to change the light when approaching them.

      Emergency vehicles don't have a remote control. They have a strobe on the vehicle that is not able to be seen by the naked eye, but is picked up by a sensor on the mast arm or span wire of the traffic signal. That sensor then tells the traffic signal controller to put the cross street into a red phase, allowing the emergency vehicle to safely pass through the intersection.

    They are far behind proper traffic light efficency. The city planners and engineers agree to make the road lights as inefficient as possible in order to create "compunded stresses" on the roads.

      Garret Morgan didn't invent THE traffic light. He invented A traffic light. His 1922 invention looked nothing like the traffic lights we know of today. The lights we know today more closely resemble a signal designed by William Potts in1920. Morgan did make out pretty well, though. General Electric bought the rights to it, netting Morgan a sweet $40,000. That's equivalent to about $600,000 today. Morgan should be more revered for his Safety Hood invention, which would become the gas mask, literally saving lives in a mine explosion.
