All lights are independently controllable. 'Front' and 'Rear' lights are the red and white lights respectively at once end, 'FO1' and 'FO2' are the red and white lights at the other end. By default these should be mapped to F1 and F2. I have a Bachmann/Zimo decoder in mine and have set it up for all combinations of headlights off, tail lights off, and both tail lights on when parked.
