bright round lights

I seen around 12 round lights hovering over the road to my south. While driving west bound on 70 at the rt 256 exit . All lights was in line with a slight pitch. They was not street lights they was about 100 feet or so above the street lights. I had to look a couple times because it was definitely something I never seen before and drive this road every day same time. Traffic was light but every body slowed down i was thinking are they seeing this also. Would like to add it was very foggy at time however was definitely different looking..
