Hello y’all. I live in Phoenix, AZ, and was traveling down to Yuma to go see family. Im 32 years old, grew up in Yuma; have spent many, many years going to and from Phoenix both as a kid and as an adult. Always went through the i85 through Gila Bend, passed by the women’s prison. And in all the years that I have traveled through, I have never seen anything like this. I saw it first Tuesday (02/11/2025) when I was heading down to Yuma (i85 south around 12:02am in the morning), pulled over and took a quick video when it disappeared right before my eyes. I waited for a couple minutes but got spooked (I’m curious but don’t wanna get myself abducted lmao) and continued on with my drive. 
Fast forward the next evening, I’m on my way back up to Phoenix and I see the exact same thing on my drive back. About 20, maybe 25 minutes outside of Gila Bend, and literally right before the prison. So I pulled my phone out and started recording (I know I know that’s dangerous and extremely risking and I don’t condone it whatsoever. Make sure you’re driving safe). It’s definitely spooky to me how once I passed by it, it fades down from four lights, to two, to going absolutely dark. Does anyone have any idea what this could be?

The video attached is one of 4. This is the second video I took Wednesday night, when I had turned around to go see it again. I took a 20 second video the first time I saw it on Tuesday; took a video before this one of me passing it the first time on Wednesday (1 minute 20 seconds), and then a final time when I had turned back around towards Phoenix where you barely see it for a second and it’s completely dark the entire video (1 minute 24 seconds)
