Abstract:
Systems and methods for reducing a risk of vertigo flicker caused by a notification appliance are provided. Some systems can include the notification appliance measuring an ambient light level, the notification appliance determining whether the ambient light level is lower than a threshold, the notification appliance activating a constant light source responsive to determining that the ambient light level is lower than the threshold, and the notification appliance activating a flashing light source after activating the constant light source.
