So I was just driving home from my wife’s house close to the argyle, Texas area just before midnight when I stumbled upon this faint strange light beam in the distance. I stopped my car and took a video of it and it made me perplexed. I decided to drive and follow this strange light and got on I35 heading north towards Denton. As I got closer to it on the highway, it was on my left hand-side and it became a dazzling strong blue color. I was near the Northlake city area. I couldn’t believe my eyes i’ve never seen anything like it. It just didn’t feel natural to me but I didn’t know if there was a satellite or something that artificially created this. I was trying to stop on the highway and get out to film but decided to get even closer to see the origin of the light but as I was driving on the highway again it started fading and disappeared. I was disappointed but after maybe 5-10 seconds it formed back again to a full light and stayed on for another probably 10 minutes before fully disappearing for good. I was so close to getting the ground point but lost track as soon as it was gone. My best estimate of where it could have been around a few mile radius from this point: (33.1085975, -97.2435854) Anyone have any idea what this is?
