Florescent orange boomerang shapes

I was just a kid riding in the car with my mom vising family and didn't want to be there so I was ignoring the inside of the car and watching the stars in the county sky.  I remember begin confused then dumbfounded by three seemingly connected but not, florescent orange boomerang shape lights that would flash (seemingly) randomly in the south western sky.  This continued until we were too far and or the tree line blocked my view.   Maybe about 3 mins. or so.   It didn't stop or disappear, so it probably lasted longer.   Wish I had said something now, wish I had gotten Mom to stop the car.   We were in SE Guilford county just off of I-85/I-40 near what is now Lucent Technologies, but at the time was AT&T.  I know I was a kid (around 11 or 12), but I will never forget it and I also have always had a very vivid knowledge of the geography of the Greensboro area so I am 100% on where it was.  I didn't mention it to my Mom at the time because well, like I said, I didn't! want to be there with her anyways so I kept this wild thing to myself.
