  1. Develop a filament material that emits light when an electric current passes through it.
  2. Seal the filament inside a glass bulb filled with an inert gas to prevent it from burning out.
  3. Connect the filament to an electrical power source with a properly designed socket.
  4. Test the bulb for efficiency, longevity, and safety before mass production and distribution.
