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.
