1. An e-vaping device, comprising:
a cartridge, the cartridge including,
a reservoir housing at least partially defining a reservoir, the reservoir configured to hold a pre-vapor formulation, and
a vaporizer assembly configured to draw the pre-vapor formulation from the reservoir and to heat the drawn pre-vapor formulation to form a vapor; and
a power supply assembly configured to supply electrical power, including to the cartridge to cause the vaporizer assembly to form the vapor, the power supply assembly including
a power supply configured to supply the electrical power;
a coupling interface configured to electrically couple the power supply to the vaporizer assembly;
a first light-emitting device configured to emit light, the first light-emitting device adjacent a first side of the coupling interface;
a second light-emitting device configured to emit light, the second light-emitting device adjacent a second side of the coupling interface opposite the first light-emitting device;
a first light tube structure having a proximate end and a distal end, the proximate end adjacent to the first light-emitting device, the distal end extending through the coupling interface; and
a second light tube structure having a proximate end and a distal end, the proximate end adjacent to the second light-emitting device, the distal end extending through the coupling interface, the first light tube structure and the second light tube structure configured to channel the emitted light from the proximate end of the first light tube structure and the second light tube structure to the distal end of the first light tube structure and the second light tube structure, such that the first light tube structure and the second light tube structure are configured to emit the channeled light into the reservoir housing of the cartridge to cause at least a portion of the cartridge to emit at least a portion of the channeled light to an external environment.
