big,hovering triangular object with multiple lights lit under it gliding at low altitude on a clear,calm night

i was on my way to work on jasper road,rigth after 58th street.i had just gone past t traffic lights on 58th street and was now slowly accelerating on jasper road...after the lights,the road is just a little elevated so you have a wide and open view of the sky.As i was driving,something came to my eye.I noticed a triangular shaped object,with six amber lights or so and a middle yellowish-blue blinking one in the middle.What made me notice it is that it was gliding/hovering at prety low altitude,steady speed and it caught my attention because there's no airports close around and it didnt make sense to me why there would be a low flying aircraft right there.I pulled my car to the side and since i had a wide clear view,i decided to look a little closer at whatever was slowly hovering ahead of me...and by no means was it a helicopter because there was no blades whirring and no noise coming from it.I had just slept for 7 hours before getting up and ready for work! so i was fully rested,awake,sober and straight minded at that point.I watched this thing slowly glide while emanating no noise from it for a good minute and a half or so.If i could approximate,this thing was probably 1/2 a mile away but from that distance and by what my eyes were telling me,it looked pretty huge....this just happened 2hours ago so forgive me for the way im writing all of this down but im still awed,dumbstruck and scared from whati saw...i will never EVER forget that moment as long as im living and breathing on this earth
