4 dim lights lt orange in color flying extremely low just above redwood tree line totally silent

I walked out on my back deck. I noticed it was extremely dark out and extremely clear sky.  something made me look up when i did i noticed 4 lights moving on an object directly above my home.  It was absolutley silent the 4 lights were under the object which appeared to be in somewhat of a square in shape the lights were not bright they were dim and had an orange tint. it was moving from the south (away from the ocean) to the north, it seemed to be flying just above the treeline (redwood tree) of the tree next door it moved at a slow steady speed as it passed over my house i yelled for my wife as I ran through the house to front door in hopes it would still be in view from the front yard.  it was gone.  It took me a few minutes to comprehend what I had just seen.  I phoned 911 to inquire whether anyone else had reported seeing any strange low flying objects, i was referred to the faa.
