at night time, does the cop have to have lights on in order to be out doing radar? Why I ask: I was going down I-675 south a couple exits before I-75 south. It was about 10pm, and dark outside. I clearly saw a police officer at the bottom of the hill, with the police car door open, and him leaning on it, shooting radar. All of the car's light's were off, including the siren's. His interior dome light was on. Maybe even a map light. But nonoe of that was visible until I was directly across from the car. If he would have gotten someone for speeding, would it have been legal?
