Traveling East on HWY 16 between communities when the event occurred. Started off as a single green/blue light when it entered my line of sight and split into 3 lights traveling in tandem/tridem. The object/light was moving South East from the Northwest, seeming in a downward angle. The light(s) passed underneath the moon, starting above/beside on the west side and ending underneath on the east side. As it passed under the moon it broke into three identical lights before it disappeared. The object(s) traveled approximately 6-10 inches across my windshield before disappearing into the atmosphere.
