Which additional light is noted when the cabin area lights are activated?

When the cabin area lights are activated, the dome light at Row 13 is specifically designed to illuminate that area as part of a wider safety and comfort design in the aircraft. This additional light provides extra visibility for both flight attendants and passengers in that section of the cabin, particularly during boarding, deplaning, or in the event of an emergency.

The activation of cabin lights ensures that all areas are adequately lit for the safety and awareness of passengers and crew members. The additional dome light in Row 13 serves to enhance visibility in that specific location which can be pivotal in managing the cabin environment and ensuring that any messages or instructions can be seen clearly.

Other lights, such as reading lights and emergency exit lights, serve different specific functions and are not a direct addition that comes on specifically with the activation of the cabin area lights. Hence, while they are important for their respective purposes, they do not fit the context of the question as to which additional light is noted when cabin area lights are turned on.
