Lights on a oval/disk craft with rotation

Driving into Centralia on US-51 from Irvington, I looked to my left (west) and saw lights in a slight diagonal curved row. We pulled over on the side of the road (near Country Bobs) and watched as the seemingly stagnant object floated, then rotated slightly, and started to shut lights off shut off before it disappeared in a blink of an eye. While watching it, you could see a faint outline of a craft in the dark sky. This all happened within seconds. We did not hear any unusual sounds. The area that this happened in is mostly farmland with scattered houses.
