The term refers to the indicator light on a specific brand of disposable electronic cigarette. This light typically activates during inhalation, signaling proper device function. A lack of illumination can indicate a depleted battery, a connection issue, or another malfunction. For instance, a user might observe the light ceasing to function while puffing, suggesting the device has reached the end of its lifespan.
Understanding the function of this indicator is crucial for users. It offers immediate feedback on the device’s operational status, allowing users to troubleshoot potential problems or replace the unit as needed. This visual cue simplifies the user experience and contributes to the product’s overall convenience. Historically, disposable e-cigarettes have lacked such clear indicators, leaving users uncertain about battery life or device functionality. The introduction of indicator lights represents a significant improvement in usability and user experience within the disposable vaping product category.
