While watching perseid meteor shower with my girlfriend, two of us saw two strange white/yellow lights going toward each other in a very strange way and it looked like they will colide into each other. Few seconds later they avoided that possible colision and disappeared very quick one to the SW and other towards NE. They didn't look like airplanes and had no other lights other than that yellowish one. Also were very high in the sky and really fast moving and changing directions.
