For night VFR, which item is additional instrumentation required?

For night VFR operations, the inclusion of adequate lighting for each required instrument or indicator is essential to ensure that the pilot can effectively monitor the aircraft's instruments in low-light conditions. This is important for maintaining situational awareness, as the visibility of these instruments directly impacts safe aircraft operation. Properly illuminated instruments allow a pilot to read altimeters, airspeed indicators, and other essential flight data, which is critical for making informed decisions while flying at night.

While navigation lights are important for visibility to other aircraft, they do not aid the pilot in monitoring the aircraft's status or performance. Emergency towing equipment and passenger safety briefing tools are not specific to the requirements of night VFR flying. They do not fulfill the immediate need for instrument visibility in low-light environments. Thus, the requirement for instrument lighting is specifically tailored to the unique challenges presented by night flying, making it the correct choice for this question.
