The correct answer is D) automatically when the raft is inflated. The lights on the outside of the canopy of an inflatable liferaft are designed to activate automatically when the raft is inflated, in order to provide illumination and visibility for the raft at night or in low-light conditions. This is a safety feature required by U.S. Coast Guard regulations for inflatable liferafts to aid in the location and identification of the raft. The other answer choices are incorrect because: A) the lights are not operated by a light sensor, B) there is no mechanism to turn the lights on by rotating the globe, and C) the lights do not have a manual switch to activate them.
