Bright Light approx 3 miles able to get under it with sunroof open

We were leaving a friends home and as soon as the car was facing west on Baya Ave we noticed a very large bright light hovering in the near distance.  We proceeded west on Baya to the intersection with US 90 west, a traffic light stopped us directly under the object that was hovering/with the sun roof open. There were many other cars stopped as well.  I knew that many others had to witness this event.  The object had a large round ball of light at the front with what appeared to be 2 prongs sticking out of the rear at an angle of 45 degrees, ladder like silver colored things seem to connect the prongs.  We were under it for the entire red light, it then made a sequence of beeps (computer noise) is what I called it then and diappeared within 2 seconds completely out of sight.  I did a u-turn at the light and went directly to the Lake City police station where we filed a report. I told the officer I did not want him to think I was crazy, but I was shaking, overtaken by the event.  He explained to me that he did not think us crazy at all, because himself and a group of officers were called to a home in south Columbia county where a craft hovered directly over 5 police officers and took off @ a speed as unbelievable as the one I had described.  I still get goose bumps to this day talking about it.  This is the only report of this kind I have ever made. I might add the car stereo and lights reacted strangley for a few moments.  The cassette player kept rewinding the same song.  The car stalled briefly. The clock lost time.
Date is approximate.  PD
