Verified answer

Cleveland, Ohio, is widely credited as having the first stoplight. James Hoge, an engineer, hooked up the first traffic light to the trolley line's electricity in 1914, using the red and green lights that were already familiar from their use by railroads. The light was controlled by a policeman in a booth nearby, who would flip the switch between red and green. The yellow light didn't come until later; it was an invention of William Potts, a Detroit police officer.

Technically, there were several experiments with traffic lights before Hoge's success in Cleveland, but none of them took off like his did.

What did came first the vehicles or the traffic lights?

Logically, unless there were reasons to control traffic, there would have been no reason to create or install traffic lights. Because "traffic" generally comprises vehicles (motorized or otherwise), the traffic was probably there prior to the lights. Certainly, there were mechanical traffic signals that preceded traffic lights, not to mention traffic officers who once stood at busy intersections to direct traffic on a regular basis.
