Abstract

Presented herein are devices/apparatuses having indicator lights (visual indicators), such as light emitting diodes (LEDs), positioned underneath/below the outer surface of a housing of the device. However, the indicator lights positioned below the outer surface of the housing, sometimes referred to herein as “sub-surface” or “sub-housing” indicator lights, are optically coupled to the outer surface of the housing via one or more optical connectors (e.g., light guides, light pipes, light diffusers, etc.). As such, the light emitted by the sub-surface indicator lights is still visible at the outer surface of the device housing.
