1. An apparatus, comprising:
a housing including at least one port;
a functional element positioned within the housing;
at least one light source that is separate from the functional element and positioned within the housing; and
at least one translucent member disposed in the at least one port such that light emitted from the at least one light source is observable outside of the housing via at least one translucent member located at the at least one port, and:
(i) wherein the at least one translucent member is a gasket configured to mount the functional element to the housing and to create a seal between the functional element and the housing; or
(ii) wherein the at least one translucent member comprises a functional element membrane configured to be attached to an outer surface of the housing; or
(iii) wherein the at least one translucent member comprises an optical insert disposed in the at least one port, wherein the optical housing insert includes a cavity to retain a functional element protector therein; or
(iv) wherein the functional element is a microelectrical systems (MEMS) microphone electrically mounted on a printed circuit board (PCB) within the housing, and wherein the at least one light source is also electrically mounted on the PCB.
