Some have sensors which will indicate that a car is at the intersection, some have pressure plates at the intersection which detects the weight of a vehicle on it, some are just timed.
You can only have red lights on the rear of your car. And blue lights are illegal to use on any car on the street they are only for emergency vehicles blue lights are for police only
red lights are critical lights. may be a door open or loose or may be something serious. what type of car is it?
Locally to me, the blue bar on the top of the car flashes (in some other states, I believe police use red lights, or red and blue) the headlights flash and the tail lights flash.
White.
The lights are still in this order: RED YELLOW GREEN
The red ones in the rear of the car. Note: They are separate from and next to the red lights that are on constantly when you turn your head lights on.

Some red traffic signals use vehicle detection systems, such as inductive loop sensors, which activate when a car is positioned at the stop line. These sensors ensure that the signal only changes when a vehicle is present, reducing unnecessary delays for vehicles at intersections. This technology helps improve traffic flow and minimizes waiting times for drivers who are stopped at red lights.
when you see there tail lights. White lights travel farther then red lights.
You stop ! The blinking red indicates the lights are about to change to green for the traffic.
