Fun fact: they dim the interior lights when you're landing at night so your eyes are already adjusted to the darkness if an evacuation is required. It's not always noticeable since they are sometimes already dim (especially on later flights when people might be trying to sleep, but they will turn the lights on for their safety check and then turn them off again).
