The dim lights are all that we could see with no flashing. And no visible trail or sound.

my friend and I were on my back patio smoking cigars and I noticed a group of what I first thought was a small group of birds but quickly realized it was not. It was 4 dim lights, 3 in a triangle formation with the 3rd just outside the triangle traveling from west to east. I have no idea how high they were so I have no idea how big the craft was. They appeared to be traveling at a very high rate of speed and did very slightly from flying in a straight line. we observed them until we could not see them anymore. The event only lasted about 6 seconds. And we also noticed that they made no sound that we could hear.
