I was driving to work at around 4:30am. I was driving over a pass known as Razorback mountain, a known hotspot for UFO activity. I noticed a bright, orange flashing low in the sky to the north east. Bright enough to light up the surrounding sky, At first I assumed it to be a very odd coloured lightning that I've never seen before, as it was as bright as lightning and giving off a lot of energy, but as I observed it for the next 20 minutes whilst driving that didn't appear to be the case, as the flashing seemed very regular, not the random flashing of lightning, more like the flashing lights you'd see on a plane but much, much brighter. It was also very localised in one small spot and looked like it was almost a long diamond shape. I was able to determine that it was fairly close, a couple of miles away at most at my closest point to it, due to the fact it was stationary and it didn't take long for me to pass it. After seeing it in the distance in front of me, within about five or six minutes I was passing to the left of it, and not long after that I could see it in the rear view mirror. I've been driving this route in these early hours for 13 years and have never seen this.
