Abstract
A power supply assembly for an e-vaping device may include a coupling interface configured to couple with a cartridge to configure the e-vaping device to generate a vapor, a light-emitting device, and a light tube structure extending from the light-emitting device and through the coupling interface. The light tube structure may channel light emitted by the light-emitting device to emit the light into a reservoir of the cartridge to cause at least one portion of the cartridge to emit at least a portion of the channeled light to an external environment.
