lights floating in the air

This is an old one, but I want to tell it.  I worked afternoons in Oklahoma City and was commuting  back home down the freeway one night.  There was a lot of traffic going both ways. I was heading east on I40 near Choctaw OK and noticed a couple of lights off to the left, north of the freeway, up in the sky.  At first, I thought it was an airplane as Tinker AFB was about 5 miles away, I just went past it minutes earlier.  Here I was, driving down one hill and heading back up another, when I noticed a pair of lights that were stationary up in the sky, north of the freeway.  Just floating maybe a hundred feet up or two hundred. I thought it was weird, because I thought it was incoming aircraft like right next to each other in the sky.  Maybe 50 feet or a hundred feet apart.  Way too far apart to be a helicopter.  They did not move at all, and I thought maybe it was a work crew on a cell tower, with lights, but drove back to work the next day in the daylight and there ! was no tower there, or anything else.  Then a couple of nights later I saw the same thing, same area but south of the freeway.  My buddy was retired Air Force,  I asked him did the Air Force have anything like it and he just shook his head no.
I opened my window, and tried to see it, but traffic was moving fast so I just drove on.  All I could hear was the traffic and the wind.
Source of report indicates that the date of the sighting is approximate.  PD
