Large circular cluster of lights, approximately 25-30' wide, approx. 100' above the ground was observed.

Driving home at night; time was approximately 10 in the evening.  I was heading west on a road near Meade Lake and eventually would turn left (south) on a side road which had me heading towards St. Rt. 140. While heading west I saw a very bright light to my left.  As I turned on the side road to head towards St. Rt. 140, the light was directly ahead of me, probably a bit less than a 1/4 mile.  It appeared to be over the road and not moving.  I noticed there was a car in front of me and behind me.  We all slowed down as we approached the light.  It appeared to be a circular cluster of lights (similar to a hosptial operating room light) that was as wide as the two-lane road.  All three of our cars slowed to almost a stop as we drove under the light.  I estimate that the light was probably 100' from the ground perhaps.  I rolled my window down thinking that perhaps it was a helicopter but there was no sound except for the cars.  I continued under it and turned right on St. Rt. 140.  I became quite a bit frightened as I drove down 140 because I began to think that it wasn't something normal, that perhaps it was a UFO?  I then began to think that whatever it was, it had to have seen me drive under it.  To this day I wish I would have pulled over some distance away from it and watched what it did.  I told some friends but never formally reported it out of fear of ridicule.  Later I heard a lot of people out in that area had seen something strange in the sky that moving around.  I am an electrical engineer by profession.
Witness indicates that the date of the event is approximate.  PD
