Abstract: A high visibility safety vest assembly includes first and second elongated illumination assemblies positioned on a front portion of a vest, and third and fourth elongated illumination assemblies positioned on a rear portion of the vest. The vest includes a material layer. A high visibility safety vest assembly also includes a power supply having a rechargeable battery and supported by the vest. A control device is electrically coupled with the power supply and each of the first, second, third and fourth elongated illumination assemblies. The control device is configured to selectively facilitate provision of electrical power from the power supply to the first, second, third and fourth elongated illumination assemblies. The first, second, third and fourth elongated illumination assemblies are positioned such that, when the vest is donned by a person standing upright, each of the first, second, third and fourth elongated illumination assemblies are generally vertically oriented.
