Abstract

Systems, methods, and other embodiments described herein relate to synchronizing the presentation of vehicle exterior lights to reduce the sensory overload of a pedestrian. In one embodiment, a method includes assessing a sensory environment of a pedestrian. The method also includes determining that the pedestrian is in a sensory-overloaded state based on a characteristic of the sensory environment and sensor data indicative of a pedestrian state of mind. The method also includes synchronizing a presentation of a first vehicle exterior light and a presentation of a second vehicle exterior light based on a determination that the pedestrian is in the sensory-overloaded state.
