I saw some strange orange lights last night in a triangle formation while at work.      They were pulsating from dim to bright, but they had no strobes, or beacons like a normal airplane would. They got real close together at one point and spread out again back into a triangle.  I saw a couple more after those,  but they were not in formation after that, and then I called the control tower because they looked to be in our airspace and I hadn’t heard them announce their presence on the radio, but of course they disappeared about that time too.  The control tower said they weren’t picking up anything on their radar or the like either.  
 

Maybe some drones or a secret military operation.  I dunno, but it was weird. 
 

I caught a crappy video of the very last one I saw.    Just looks like a blinking light, nothing special, and I don’t think they were aliens or anything lol, but I’m very curious as to why none of them were being detected on radar.
