A method for operating a signal system, in particular for a vehicle, a gaze direction of a user being monitored by way of at least one first sensor, a warning signal being outputted depending on the gaze direction detected. Provision is made that by way of at least one second sensor, an environment of the user is monitored for possible target objects, the detected gaze direction of the user being compared with the environment. When the gaze direction of the user points toward one of the possible target objects, that target object is designated as a selected target object and, depending on a triggering command of the user, the warning signal is outputted into the environment for the selected target object.
