many yellow lights arranged in two angular shape, with significant space in between those light anglesI was on a way to Mall with my wife on two wheeler when my wife saw the flying body and screamed what is it, when i looked i could see two the lights at corner (covering some space of the corner of triangle, they were yellow in color and it was about 500 ft above the ground i think and was huge, it was making a sound and was moving very slowly than a plane would move at that height, I tried to records but camera quality of my cell phone being bad i could not see the lights in my camera, however i think it should have captured it.it was more like hovering and moving instead flying, it was moving in a curved path.Shape was Triangle and it was dark, very dark indeed and how did i figure it out it was triangle is because it was having yellow lights at two corners not the third one, Lights were spaced apart and were somewhat in an angular shape so i could just figure out it was in a triangle shape.
