Methods and systems for illuminating a path are described. Data indicating a condition can be received by a lighting device. A light for output by the lighting device can be determined based on a location of the lighting device, such as a location of the lighting device relative to the condition and/or an egress. Data indicating the condition and/or data indicating the light for output can be transmitted to one or more other lighting devices, thereby illuminating a path away from the condition to the egress.
