Not sure if they're correct but the AI only has 2 white headlights at the bottom showing when going forwards in the CTC-3 cab car. When I set up the cab its only "dim" (top headlight only) or "bright" (top and bottom 2 headlights).
Here you see the AI headlight configuration in services and scenarios This is player control "dim" headlight This is player control "bright" headlight
