A flashing red traffic light is treated the same as a regular red traffic light because it indicates that drivers must come to a complete stop before proceeding.

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.
Gas light was used before the electric light and before gas light, candles were used.
Before the introduction of traffic lights, various methods were used to manage traffic at intersections, including police officers directing traffic and simple signals like flags or lanterns. Additionally, some cities experimented with mechanical devices or signs to indicate when vehicles should stop or go. These early systems were often inefficient and could lead to confusion, prompting the eventual development of standardized traffic lights to improve safety and traffic flow. The first electric traffic light was installed in 1914, leading to the modern systems we use today.
A yellow light on a traffic signal means to slow down and prepare to stop before the light turns red. It serves as a warning that the light is about to change.
