very large lights in a row.

This has bothered me for years.  I was driving home from work in the late '80s.  I think it may have been 1988, possibly 1 or 2am.  There were a row of huge lights, I think I remember them to be vertically oval.  I was on Rt 6&209 going toward NY.  The lights were in the sky connecting each side of a valley in the mountain, on the other side of Rt. 84.  This would be approximately across from where Walmart or Kmart now are.  I could see the sky above and below the lights.  I never stopped the car.  I remember thinking to myself that I didn't remember houses there.  The next day, I saw that there weren't.  There is no other explanation other than there being a UFO floating in the sky.  I would love to hear if anyone else remembers seeing anything there.
