A display system that includes a housing, at least one light source, a diffuser, and control circuitry is provided. The housing can have an internal wall and a signal indicator region. The at least one light source can be located within the housing. The diffuser can be disposed between the at least one light source and the internal wall. The control circuitry can be electrically coupled to and operable to cause the at least one light source to emit light that passes through the diffuser to the signal indicator region. A method for displaying signals in a headset including a signal indicator region is provided. The method can include emitting light from at least one LED. The method can include transmitting the light through a diffuser and onto the signal indicator region. The diffuser can include a substantially transparent substrate in which a plurality of translucent particles are embedded.
