1. A navigation system comprising:
a tracker having at least one trackable component;
a localizer configured to track states of the at least one trackable component within a field of view;
an illumination assembly located remote from the tracker and operable to direct a visible light within the field of view; and
a controller coupled to the localizer and to the illumination assembly and the controller being configured to:
receive the tracked states from the localizer;
determine a status condition of the tracker based on the tracked states received from the localizer, wherein the status condition identifies whether or not the tracker is being properly detected by the localizer; and
control the illumination assembly to remotely direct the visible light at the tracker such that the visible light reflected by the tracker from the illumination assembly is visible to a user of the navigation system to communicate the status condition of the tracker.
