During my drive from Los Angeles to Phoenix, I spotted lights in the sky that I couldnt explain. At first there was 3 bright lights (of a orange/yellow color), appeared to be in the formation of a triangle. They didnt move, but hovered in the air. They were a good distance away, but still very bright. They were low enough to seem close, but high enough not to be a tower or connected to the ground. After about 5 mins of watching these, another set of 3 lights appeared nearby the first set. For a few minutes you could see both units hovering nearby each other. Then the first set disappeared quickly.
