GeekVape devices often come with LED indicator lights that convey important information about the device's status. While the specific meanings of the lights can vary between different GeekVape models, here are some general guidelines: Battery Status: Typically, the LED lights indicate the battery status. A green light might indicate a full or high battery, yellow for medium, and red for low. The number of flashes or the color sequence can vary. Device Activation: When you take a puff or press the fire button, the LED may light up to indicate that the device is actively delivering power to the coil. Errors or Issues: If there's an issue with the device, like a short-circuit or low atomizer resistance, the LED lights might flash in a specific pattern to alert you to the problem.
