Saw 1 black triangle flying East at low altitude. It was dark out. Solid green lights on 2 front corners, red light on back corner.

I was driving south-west at night. There was an apartment building to my left and storage facility to my right. Above the storage facility were two green lights. They were east-bound, heading towards me. As they got closer, I could make out shape of a triangular craft, with the green lights situated on the two front corners. There was a triangular bevel under the body of the craft , which was nearly as dark as the sky. As it passed overhead, I made a U-turn in the driveway of the apartment complex to view the craft from behind. I could only see one red light, presumably the back corner of the triangular craft, heading east (towards downtown Kansas City).
The craft moved at a steady pace. I’m not sure of scale, but it seemed lower to the ground than an airplane or helicopter. It made no noise and left no trail. There was no one else on the road at the time. There was one car leaving the apartment complex as the craft exited my field of view.
I parked in the apartment complex and immediately tried to call my brother. The call dropped several times (at least 5). I could not reach him until I got home. I usually wouldn't have thought much of it, but decided to report that detail as technological disruptions sometimes accompany UAP sightings.
An illustration is attached.
