Cone shaped thing over the ocean

I was on my balcony looking at the ocean and saw a cone shaped thing with a weird flight pattern flying. It was just too straight. Thought I was seeing a plane wrong, but the more I watched it was cone shaped and the green light that it was emitting was like a beam and it wasn’t a star. I finally said out loud (but didn’t yell) “hi, can you hear me?” And the green light went out and I never saw it again. I recently saw a coastal news article with a lady’s picture from 2014 and it looked exactly like one of those cone shaped things in her picture over the pier. That’s how I found this site.
