While driving home at night I saw a number of mustard-yellow spheres in the sky (low altitude). Two sets of three were in v formationIt was dark and I was on my way home from work and driving on a busy road through a residential area when I saw off to my right ahead of me there were a number of large round mustard-yellow lights (approximately 10 to 15) in the sky that were simply hovering and not going anywhere. Each one appeared to have one round yellow light (without a beam) that I could see, and I could not hear any sound. Two sets of three lights were in a “V” formation. I saw the two “V” formations slightly move once for each of them. The two “V” formations were parallel and the others were spaced around and between them in a general congregated area. These lights were not like airplane lights. The lights stayed consistent without any flashing, blinking, color change, beam or any change at all.These lights appeared larger than the lights we normally see in the sky on regular airplanes and jets when flying at the same level. These lights were not at a high altitude, but not close enough to see other details in the dark. This sighting was over a busy, small city and I could not tell if they were positioned over the business or residential district.I did not see any other aircraft in the sky at that location. It was not raining and there was nothing obstructing my vision until they were hidden by trees as I passed by in my car. I do not have a camera phone so I was not able to take pictures.
