Abstract
A system and method of illuminating a target object even when the target object is otherwise well illuminated by ambient light. Retroreflective material is provided on the exterior of the target object. The retroreflective material is pigmented to primarily reflect light within a predetermined frequency range. An illumination assembly is provided that contains a first light source and a second light source. The first light source and the second light source produce beams of light that are perceived stereoscopically. The primary wavelength of each of the stereoscopic beams of light falls within the predetermined frequency range. When the beams of light strike the retroreflective material, the retroreflective material shines even in bright ambient light.
