It started off as three golden roundish circles that were close together and then moved apart then others came in an arc over the houses where they all moved around slowly then some would vanish then others appeared, all golden all about the same size and shape.

They just seemed to grow smaller til there was nothing left OR they were zooming straight off ahead of me, giving the appearance of growing smaller

There was no sound at all, we heard a slight rumble but i don't think it was associated with the lights, they looked like balls of fire and sometimes four would shape into a diagonal, three went into a straight line and the middle one 'vanished' two looked as though they collided but were both ok and carried on moving til they vanished, none went over our house they all disappeared at around the same place.
