I was driving west on I40, west of Needles, CA. about 3:30 am. There were many semi trucks on the road who probably saw this, too. It is a very desolate desert area.Suddenly a bright blue light illuminated my whole car from above. Even though I was alone, I said "what the hell is that" and had to lean forward to look up through my windshield. I saw a huge blue light streak from above my car off to the right side of the road. It stopped in mid air and appeared to be a extremely bright, icy blue colored ball.It then flashed even brighter and vanished. It did not hit the ground as say a meteor might. The only visible color was blue. I had no way to determine the real size or distance from me. A grapefruit held at arm's length was about the size of the ball as I could see it from my car.I am a professional artist and have never seen a UFO or anything like this before.
