As I was driving home from work, taking the same streets I always do, at around 9:45 at night as I was aproching the intersection of Willard st and route 113, it was a red light so I was taking my time to get to it. I happened to look up and saw three white lights in a perfect triangle moving in a straight line across the sky. About as bright as the lights you'd expect from a helecopter or airplane but dead silent and never wavering from the perfect triangle form. I followed it to the street light and as I continued to watch from inside my vehicle the three lights began to fade one by one. Starting in the rear right corner the lights went out one at a time ending with the on in the front.
