The jacks were provided as a convenience. The “IGN terminal was for (I believe) hooking up a battery if the magneto needed a boost for easier starting in cold damp weather. The LIGHT terminal may or may not have been for a battery boost to the light as well, I can’t swear to it. I do know that on the N’s that I’ve had, I got the light working but it was (like myself) not terribly bright and I’m not sure how much good it would have done. As a night fishermans aid, I have doubts about how useful it would have been, because you did have to run the motor in order to have the light working. I’ll leave it to your imagination about what kind of task was doable with both hands occupied running the motor…
Here’s an extremely low quality video clip of a running model NS with the light (sort of) functioning
and some other pics of the same motor

He's livin' in his own private Idaho..... I hope to go out quietly in my sleep, like my grand-dad did..... and not screaming, like the passengers in his car...
