Abstract: An entry step lighting system for a deployable aircraft stairway. The system includes steps that having integrated light sources that direct and provide illumination to the steps. Some light sources illuminate strip lenses which indicate proximity to the step edges. Light emitted by a second group of light sources is directed into an angled face established on a riser wall between each step. The light bounces off of each angled face to illuminate the step below.
