Okay, we’re sure it’s not UFO’s! There were 8 almost candlelit appearing “launched” things that flew into the sky from south of Genessee hill, over the water toward Vashon. It was cool! Don’t know the contraption that could launch something like that! The lights dissipated, or “went out” on their own…
They’re called Sky Lanterns. It’s a paper balloon with a fuel source that’s lighted at the bottom: think mini hot air balloon. The sky lanterns you saw were part of a ceremony for someone who had passed away.
