Coming home from work sometime around 9:40 at night traveling eastward on highway 4. I looked to the left and noticed the lights that seemed to be fairly low over the bay. I first thought it was a airplane or hellicopter since the concord airport was only a few miles away. The 3 lights were small star like, 2 outer light flashing, inner light not. The lights stayed in place not moving for several minutes as I was now driving into Pittsburg; which is why I began to think it was not a aiplane or hellicopter. I also noticed there was no other colored lights. As I was entering Antioch and checked to my left again, the lights were now traveling eastward no longer at the angle but horizontal and the lights were no longer flashing but solid. I lost track of it for a few minutes but as I pulled into my street, which is a court, the end is open facing the freeway North, I could see the lights. It seemed to turn/spin around so that 3 larger lights now faces me. So I guess the small star like lights in back to the large basketball size lights in front. It then moved a little westward after that and I was barely able to see it through the trees. Moments after a hellicopter with red and green or blue light traveled from southwest to north in direction of lights. I couldn't see anything after that from my house because the trees obstructed view.
