See attached photos

On my way home on the Edmunds to Kingston ferry. I had seen a large part of orca on my way there, so I got out of my car with my phone ready to take photos. There were three lights in a triangular patent at a moderate altitude off the coast of SeaTac airport and Boeing Field. The brightest of the lights had a fluid movement in a vertical Position, the light was very bright. The objects at times seemed physical when they were at their brightest, and then more oblique as they dimmed. Spontaneously they disappear. I have timestamp on all my photos and it will show you that they were there one moment and then gone.
