A safety vest is sized to be worn by a human, wherein the vest has a front and back and left and right sides each having a shoulder portion. An EL strip is provided on each side of the vest extending from the bottom of the vest upwards toward the shoulder portion. A power source is supported by the vest and connected to the EL lamp strips to supply electrical energy to the strips so that they emit EL light, wherein the EL light emitted by the EL strip is a safety yellow color, and wherein other portions of the vest are a safety orange color. Further safety articles of clothing and devices are also described, including a power pack unit.
