stop... A police officer assuming control of that intersection will have precedence over a traffic signal. If their signals are contrary to the traffic signal, you'll follow their signal.
Stop light is another name for a traffic signal.
The traffic light as we know it today was invented by Garrett Augustus Morgan, the son of former slaves. Before that there was a gas lantern signal light in England, but that was before automobiles. There was a railroad light version later, but it wasn't like our modern version. If you didn't mean "traffic light" then i don't know.
