Those flight sextants that had lights in them were made to accept a cord with a plug of some sort. The latter pugs were Cannon Connectors with three pins. There were many different configurations of these. One was even a coax. The electrical power to the cord was split; either it received power from a battery-wand, or power from the aircraft's system. In the case of aircraft it often could have been AC or DC usually 12 and/or 24V.
The Air Force Navigators Observers Association has a collection of flight sextants with all of these power configurations. Ref. www.afnoa.org , or www.usaf-nav-history.com Ron Barrett, AFNOA Historian www.ronbarrett.com
