Triangle shape the strip it look to be bounce up sideways and down really fast.

I was at work. Went out front of the restaurant to have a cigarette. I went to sit down on the bench. Light my cigarette and sat back and looked up. As I scaned the sky for stars I saw a light, at first I thought it was a shotting star butit was moving to show, So I just took my phone out to take a picture to see what it was. It didn't look right. So I got up and went to the side of the restaurant to see what it was doing. My co worker came out so I turned to him to show him and this time I recorded it because it just looked like something. So it kinda got so far away we couldnt see it anymore. So as we went back to work I started looking at the images and yes its something triangler. It looks maybe a L shape it looks like the L strip is a light. Flat on the bottom.
