There are multiple types of controls for traffic lights.
1) Signal control box can be used to change the lights as needed.
2) Some cities have remote systems that can be controlled by a central office.
3) near the traffic lights there are sensors. these sensors can see and distinguish emergency light from vehicles approaching and automatically change the lights for passage.
4) some lighting systems also recognize radio frequencies transmitted from emergency vehicles and change lights accordingly.

The right brake light does not work on 1999 Ford Windstar. Tail lights and blinking light works. Changed bulb more than once, changed the plug in where the bulb goes but it still does not work. The tag lights are not working either.
Traffic lights work on a timer, but if you look closely on the road when your stopped at the traffic lights, you should see a rectangle like shape under the car it is called a sensor And when you drive on it, a signal is sent, so the timer knows a car is waiting, if no other cars are going the other way, the timer will change and the light will go green so you can go. I hope this answer helps.
sometimes when the lights blow out the fuse also blows out. check the fuse!!
change the headlight switch !
Have you checked the drl relay?

Separate circuits.
Have an electrician check the wiring that goes to the brake lights in the trunk of the car.
I do , I'm a MP on Camp Pendleton Traffic Division. Do you have a question about them?
If the traffic signals do not work, it is to be treated as a four-way stop sign. It says so in the vehicle code.
It is noted that police cars always seem to have brighter lights than the normal cars. For one thing, the police always have their lights aimed precisely at the factory recommended settings. Some police cars in years gone by used to install aircraft landing lights in place of the bright lights for added illumination. Don't know if they still do this though. Some departments rewire the bright lights to alternately flash on a high speed pursuit for identification purposes.
