Some members of the Houston Association for Scientific Thinking (HAST) have visited the sites of the famed Marfa Lights (West Texas) and the less-publicized Saratoga Lights (East Texas). With binoculars, telescopes, and road maps, it was fairly easy for them to ascertain that the Saratoga Lights were simply the headlights of automobiles traveling along Route 787. The Saratoga display is a bit eerie but not at all mysterious, according to HAST. Below is a map of the area.

I have to take the above report to mean that the viewers were somewhere near the Bragg end of the road looking south.

The image to the left below is from the rail road history article by J. King. No info given about what camera used or exposure, or the viewing location. Was he at the point above marked 'Bragg' looking south on the road towards Saratoga? That would be the direction if the lights were car headlamps on FM 787 as the above article suggests.

The right hand image is from the National Geographic article in October 1974 that published this 20-minute time exposure which shows the light plus what is apparently a star trail, but there is only one bright star in the trail. Where are the others? Is it really a plane? No other info given about the camera used or the viewing direction, but it looks similar to the image on the left.

One big problem is that the 'star trail' seems to be going the wrong way. I can check this by using a planetarium sky simulator set for this location. I will also search for any likely bright star that could be matched with this lone image. Could it be a planet? The view is almost due south so it wouldnt be Venus. The photo was taken some time in 1964; probably the summer or spring? That should narrow the planetary possibilities greatly. Also, if this was taken after 7PM but before midnight, that should narrow the range of possible bright stars.
