Well, now I know. But I do know that there are passive inline gear indicators that you can splice into the cable run and position for easy seeing. You'd still need a helmet light to see them in the dark but helmet lights are common as salt and available at all price points. Electronic shifting and Smartphone apps or Garmin/Wahoo computers might be overkill? Just trying to keep the project in the bounds of practicality.

Kind of a condescending comment. I’m nearing 100,000 miles in 30 something years on a bike, and can state I know how to ride a bike by this time. I can still lose track of the gear I’m in. As myself and others have found, the Di2 gear indicator is very useful. Not life changing, but I do use it and like it,

I don't know of a flat-bar shifter that didn't have some kind of indicator for gear position. The ones on my Rapidfires aren't very precise but they don't really need to be. I look at them from time to time. On a tandem, hills can really mess up a commute. There is enough stuff with lights and peds and etc that on occasion I arrive at the bottom of the HILL not knowing what gear I am in. Too low and the Stoker complains. Too high and we will bonk halfway up. There is no getting started again if we stop. Anyway, to the ask of the post. A helmet mounted headlight would illuminate the passive gear indicators that all shifters must have. Seems to be the only practical solution.
Still not sure about attaching LED light with a reed switch to indicate 1:1 ratio. Probably will always shift down to 51t cog and only then will turn on the motor if necessary.
