An inflatable evacuation slide includes a flexible slide surface that is supported by longitudinal main support members. Illumination of the slide surface is provided by a plurality of illumination sources that are supported above the upper surface of the main support members on inflatable stanchions that extend upward from the upper surface of the main support members. The plurality of illumination sources may be high efficiency light emitting diodes or other high efficiency light sources. By providing an illumination source that is elevated above the upper surface of the main support members, a greater portion of the slide surface can be illuminated without shadows.
