Looked like the black triangle ufos.A triangle with a light on each corner like the black triangles that people have reported. (I just saw the lights, not the actual shape) Each light disappeared one by one within seconds. It was also by fireworks, so I'm still not sure whether it was a firework or not. (even though it was a lot higher up) And it was over the water of Lake Huron. And I only saw it for a couple seconds, because it disapeared when i looked((NUFORC Note: Witness indicates that the date of the event is approximate. PD))
