1. A hazard detector, comprising:

  • at least one hazard detection sensor that detects a presence of at least one type of hazard;

    a light sensor that senses a brightness level in an ambient environment of the hazard detector;

    a light; and

    a processing system provided in operative communication with the at least one hazard detection sensor, the light sensor, and the light, the processing system configured to;

    receive an indication of the brightness level in the ambient environment of the hazard detector from the light sensor;

    determine whether the indication of the brightness level is indicative of a dimming of one or more illumination sources in the ambient environment;

    access, responsive to an indication of the dimming of the one or more illumination sources, information representative of a status of one or more components of the hazard detector;

    select an illumination state from a plurality of illumination states based on the accessed information representative of the status of the one or more components of the hazard detector; and

    cause the light to illuminate using the selected illumination state of the plurality of illumination states.
