A Pennsylvania coal miner named Michael DeMarino invented the turn signal in the basement of his home. A father of 16 Michael never found the time to officially patent the idea. It is said that one of his youngest children fell into their 4 person outhouse the same day the first prototype was tested thus causing the invention's success to be temporarily overlooked & eventually brought to the public by other sources.
