I had pulled an off-duty officer over, at night. I aimed everything I could into the driver's side mirror, as well as the rearview mirror. I approached from the passenger side, and kept my flashlight off until I reached the "B" pillar of the drivers door, but I could see fairly well inside the vehicle on my approach. Even the officer I pulled over didn't know where I was, or from which direction I was approaching. This feedback helped me decide that, at night, this approach suited my safety concerns, while on traffic stops in the dark.
