1. An indicator arrangement for a regulator removably connectable to a facemask in a breathing apparatus, the indicator arrangement comprising:
at least one release button comprising a body operationally engaged with at least one component of the regulator and configured to be actuated by a user to detach the regulator from the facemask, at least one light source, and at least one sensor in communication with the at least one light source, the at least one sensor configured to sense at least one condition and generate at least one signal based on the at least one condition to operate the at least one light source, wherein at least a portion of the body is configured to facilitate transmission of light from the at least one light source; wherein the light is visible on or through at least one external surface of the body of the at least one release button to illuminate at least a portion of the at least one release button, wherein the at least one sensor is configured to sense an external light level and generate the at least one signal based thereon, and wherein the at least one sensor is configured to activate the at least one light source upon detecting a lack of motion of a user for a predetermined amount of time.
