Abstract: In protective illuminated vests and jackets a light enhancement means improves visibility and protects the enclosed light emitting bulb or diode. The light enhancement means is comprised of a transparent casing for housing a preferably screwbase lamp. The casing includes a cavity tapped into one end thereof for housing the lampbase and lamp, and a plurality of vertically spaced, horizontally extending apertures tapped through the casing to reflect light. The lamp is preferably mounted above the tapped apertures, beams light downwardly, and reflects in each of the apertures, giving the illusion of additional lamps.
