Lighting diagram for a car scene at night

A parked car and everything motivated: a warm dash glow low in front of the actors, a cool slash raking through the windscreen as the light they parked under, and a tube along each door frame lifting the faces a stop without a stand in shot. Everything is small, battery-powered and taped rather than rigged, which is the actual craft of car work. The plan is drawn around the car rather than a room, and the note says the one thing that ruins these scenes: turn the interior dome light off and replace it, never dim it.
