Three very large triangular widely separated lights in the sky which formed a triangular pattern.A friend was driving me to Ontario airport when we noticed 3 large triangular lights in the distance straight ahead of us just above the horizon. We were traveling East on the 10 (San Bernardino) freeway. The large triangular lights themselves formed a large triangular pattern. They were very bright and quite large. They were not planes and the sun was up already. I remarked about how odd the sighting was. She confirmed how strange it was. We both travel to Ontario airport often and had never seen anything like this. After about 7 or 8 minutes we exited the freeway into the airport and I ran to catch my plane.
