Bright orb descended from the sky and hovered over the road before disappearing

I bartend on the weekends, and I have driven this route many times before. My friend and I are going down the road, and suddenly this bright orb descends from the sky and starts hovering over the road. I pull over, and get out to observe. It's hovering, not making a sound, and it is bright and white. Round as far as I could tell. After a couple of minutes hovering brightly, it starts to flash. Eventually it dims, and we could see 4 distinct round lights on the side facing us. It would turn one light off, then back on, then two off, then back on, etc. for a couple of minutes before dimming everything and disappearing. This is my second UFO sighting here since I moved to this town 2 and a half years ago.
