1. An evacuation slide light system, comprising:
a first sensor configured to measure a pressure of an evacuation slide;
a second sensor configured to measure a stretch of a material of the evacuation slide;
a controller configured to receive a first signal from the first sensor and a second signal from the second sensor; and
a projector light located on an inflatable siderail of the evacuation slide, oriented toward a sliding surface of the evacuation slide, and operably coupled to the controller, wherein the controller is configured to determine the pressure of the evacuation slide based on the first signal received from the first sensor and to determine the stretch of the material of the evacuation slide based on the second signal from the second sensor, and wherein the controller is configured to command the projector light to emit a first image in response to determining the pressure of the evacuation slide is less than a threshold pressure and in response to determining the stretch of the material of the evacuation slide is less than a threshold stretch and to emit a second image in response to determining the pressure of the evacuation slide is greater than or equal to the threshold pressure.
