Black triangle seen flying silently in the night sky.

I saw what looked like the Stealth Bomber tonight, but with a lot of leading edge lights (7 to 10 total) the rest of the craft was pitch black, blacker than the sky. The sky is absolutely clear (it just happened about an hour ago). It was perfectly silent. I could not tell whether it was a small object close to me, or a large object far away. I was in a parking lot of apartments, so only the sky above me was in view. It was heading Northwest, in a perfectly straight line, at a slow to medium pace. The lights never blinked, and were not very bright. First time I have seen anything unexplained.
