5 bright white lights, similar to spot lights, appeared one after another and then faded away. All at different elevations.

While driving southbound on route AZ 77, in the south eastern sky, near the upper corner of my windshield 5 lights appeared, glowing from light to very bright and then fading away within 10 seconds. They appeared in random order and elevation in the sky and appeared in a row or cluster. A few minutes after they disappeared a strange electronic type buzz rang out inside the vehicle, yet nothing could have caused such an event.
