I had just got off work, and was pulling into my driveway at 10:01pm, when I saw 3 unusual lights hovering just above the crest of my roofline. I parked the car, and rushed to get out. Once out of the car I looked to see if they had moved, but they were still there. It was then that it finally registered in my mind to note the characteristics of them. They were 3 white lights in a triangle formation that were slowly pulsing on and off. Each one was about the size of an 1/8" ball berring held at arms length and the whole formation was about the size of a 3/8" berring at arms length. I was very excited to see it, but still had the frame of mind to pull my phone out and try to record video of the object. When I started recording I noticed that the lights were not appearing on my screen at all, and then they started moving towards the south west. I kept recording anyway until the object disappeared behind my roof line. My house faces directly north, and the lights started about 1/4" above the roof line. There was a nearby star that I used as reference to tell that they started out non moving, but it started moving when I started recording. After they had gone behind the roof and I stopped recording I noticed that I had no recording saved on my phone. I managed to successfully do a test record of the ground afterword. I then called my best friend and told him what I had seen. When I first saw it I figured it was a plane, however I soon realized it wasn't moving and the lights weren't blinking like a planes do. Not to mention that most planes have multicolored lights, but these were all white, and they all pulsed in unison. Given the evidence my only conclusion is that they are not any known craft or object.
