It was dusk, nearly completely dark out, I was walking from the back of my property to my house. There were no stars in the sky yet. I looked up towards the East, and out of the thin air I saw a light appear, what I first figured was a plane, as the light was way to bright and large to be a star. Then I stopped walking and realized the light was not moving or blinking at all, so, it was not a plane then. The one yellow/orange light either split into three (forming a straight line) or it like.. tilted very abruptly, showing another angle that had the three lights. Then (to me, was was maybe a half inch from the 3 lights) a fourth yellow/orange light appeared. Forming a triangle. It stayed there unwavering in anyway for maybe 15 seconds then completely disappeared, as if the lights had simply been switched off. I could not see anything in between the lights (as in nothing connecting them) its as if they were exterior lights on a completely invisible flying craft of sorts. I stood out there for another 15 minutes with out moving and hardly blinking, but saw nothing else.
