Black Triangle Sighting in Elkhart, Indiana on September 3rd 1975 – I was 13 years old and saw this ufo very close to me hoving above me

I was 13 years old, just got done playing with a girlfriend at her house in our neighborhood. It was just getting dark and as I was walking home, I saw this thing hoving very close right above me. It was like a cone-triangle shape. No sound at all. It had lights all the way around the bottom and one light at the top of the pointed cone. I was so scared, I ran home very quickly. That is all I remember about this but I have never seen it in any photos online of ufos
