What this light usually means
A blue light on a power strip usually means power, surge protection, USB charging, grounding status, or a switched outlet state depending on the model. The exact meaning can depend on the device model, the label beside the light, and whether the light is solid, blinking, flashing, pulsing, or alternating with another color.
