None of the investigations could come up with an explanation for the light. It is not an area that would normally produce swamp gas as in other cases involving ghost light phenomenon. According to folklore, the light is supposed to be the headlight of a phantom motorcyclist. There was a young motorcyclist who was racing on the road one night. He lost control of his bike and was decapitated by a guy wire supporting a telephone pole.
Greenbriar Road is mentioned in a couple of books about ghosts, but most of the information is incorrect about this road. One book claimed the road is a dirt road that is three miles long and the other book got the entire location wrong. I went there to check out Greenbriar Road and was a little disappointed at what I discovered. First the road was not in the location as described in other books, nor was it a three mile dirt road. It is a fairly heavy traveled asphalt road that is certainly longer than three miles. Since I visited the road during the daytime I did not have any encounters with a ball of light although others claim to have encountered the weird phenomenon.
Repeated Encounters with the Light
Greenbriar Light is been around for who knows how long. That was a wide sand road several years ago and everybody knew about the strange light out there so we went there to see if we could see it. We did see it but at first thought it was a one-eyed car coming down the road. It did not move toward us very fast. We were facing it and it kind of came up about a tenth of a mile in front of our car and just sit there like wavering or hovering over the road. We were facing east and we turned around in the middle of the road still watching the glowing light and when we started driving toward the west we looked behind us and the light was following our car. Just before we got to the end of Greenbriar Road it disappeared. We turned around and went back to see if we could see the light again and sure enough it popped up way down the road and again came to about a tenth of a mile in front and hovered again. We repeated this four times and each time the light did the same thing. We tried to figure out what it was but we have no idea of what it was. It looked about the size of a basketball and glowed pretty bright, not hazy or faint but a very bright whitish glow. –Paul R.
Light Comes Out of Nowhere
There is a road in St. Johns County that runs off Road 13 between Fruit Cove and a place called Switzerland that is called Greenbriar Road. There is a ghost light on this road that appears out of nowhere and it will follow your car. I saw this light with my friend Frank who told me about it. It is supposed to be the ghost of a guy that was killed while riding his bike on the road and the light is the headlight of his bike. –Jason
