Don't look; I'm changing
your not so bright
Nothing. there is no blue light.
Yellow, then red is the patterns of the traffic lights.
If the traffic light is not powered, you are to treat it as a all-way stop sign. I'm assuming that's what you mean by that. If the traffic light is broken, likely there will be utility workers out there working to fix it and you follow their instructions if any.
A yellow arrow traffic light means that you should yield in the direction you are going. These are often in place when you are turning left.

'Go'.
red light is used in traffic lights because red light has a "longer wavelength" than other colours
Stop light is another name for a traffic signal.
The red flashing traffic light means that you are to come to a stop, yield to other traffic and then you can procede when the way is clear.
A green traffic light means you may go, but only if safe to do so. If there is other traffic or pedestrians in the way, you may NOT go until safe, even if you "have the green light." Even if the other traffic or pedestrians are violating the law, you cannot go until it is safe.
The opposite would be "light traffic".
A "Green Wave" is a sensor on the traffic lights that allows the main flow of traffic to continue to have a green light unless another car is to pull up in the other direction then the light would change to let the other car go.
If a traffic light breaks most cities will assign a traffic cop to regulate traffic until the light can be fixed.
The traffic light was made in 1823.
A traffic light you seen change to green
Yes. That is why they are called traffic lights.
