[LuciaDella]

Traffic lights appeared before cars in the world. The earliest emergence times of traffic lights and cars are as follows: The earliest emergence time of traffic lights: The world's first traffic light appeared in 1868. The inventor of the world's first gas traffic signal light with red and green colors was British mechanical engineer J.P. Knight. A policeman used a lever to change the light colors by pulling a belt. Unfortunately, this light only lasted for 23 days because the gas lamp suddenly exploded, resulting in the policeman's death. The earliest emergence time of cars: The world's first car was manufactured by German Karl Benz in 1886. Later, this person founded Mercedes-Benz, becoming the inventor of Mercedes-Benz cars.
