Several airlines leave position lights on continuously, based on:
  1. The cycling on/off kills the bulbs quicker
  2. The aircraft tend to be continuously powered - therefore an aircraft observed with lights on (on the ground), can be detected as powered when it shouldn’t be. (Eg maintenance)
Obviously, if we’re talking about GA aircraft that have a full power down after flight, this wouldn’t apply.
