Essentially, yes, it was. Twice.The very first traffic lights were around even before cars. The very first traffic light in the world was located at a London intersection in 1868, and was a hand-held revolving gas lantern with red and green signals. This was not an entirely successful experiment, as the light exploded early in 1869, injuring the policeman who was operating it.African-American Garrett Morgan is credited with inventing the electric automatic traffic light which was based on semaphore. However, a Detroit police officer by the name of William Potts was the first to develop the first 4-way 3-colour light system, and it was installed in Detroit in 1920.



The first traffic light was built in front of the British House of Parliament in 1868.


Well, the first one that was used was in 1912 in Salt Lake City by Lester Wire, but the first one permanently installed was probably one in Cleveland, Ohio, in 1914. It was installed by the American Traffic Signal Company. These first ones only had red and green lights (like previous ones that used gas lighting in England). The three color ones were developed in 1920.


Yes and no.African-American Garrett Morgan is credited with inventing the electric automatic traffic light which was based on semaphore. The system was quite different to another system invented by a Detroit police officer by the name of William Potts. He was the first to develop the first 4-way 3-colour light system, and it was installed in Detroit in 1920.However, both of these systems were preceded by traffic lights that were around even before cars. The very first traffic light in the world was located at a London intersection in 1868, and was a hand-held revolving gas lantern with red and green signals. This was not an entirely successful experiment, as the light exploded early in 1869, injuring the policeman who was operating it.


The person who made the first traffic light was Lester Wire. Lester was working as a police detective in Ohio when he designed the traffic light. During the early part of the 20th century, traffic accidents were very common place.


The electric light bulb came first but was patented later that the telephone was.


Officer William L. Potts made the first traffic light


The first electric light bulb was invented by Humphry Davy in 1809. In england, and it costed 24cents.


In 1920 a traffic light was installed on Woodward and Michigan Avenues in Detroit. William L. Potts was the person who invented traffic lights. A year later, Detroit had 15 more automatic traffic lights.


In 1835, James Bowman Lindsay demonstrated a constant electric light at a public meeting in Dundee, Scotland. He stated that he could "read a book at a distance of one and a half feet".


No, just the first electric light bulb.
