Abstract: A safety vest assembly with enhanced visibility in a range of limited visibility conditions, integrated hydration pockets, and optional integrated technology is provided. The vest generally includes front and back panels with at least one band of reflective material and at least one band of lights on outward facing surfaces. Also included are pockets configured for storage of refreshments and optionally at least one electronic device. Power for the lights and additional technologies is provided by an integrated power supply, and controlled by one or more switches configured to modulate a function of the lights. The integrated technologies include a power port configured for attachment of an electronic device, a vest location device (GPS, cellular), an accelerometer, and an alert system. The safety vest assembly may be included as part of a worker safety system that includes a control system configured to communicate with a wearer of the safety vest.
