This application relates to the field of vest technology, disclosing a reflective warning vest, including a vest, an arc-shaped magnetic plate, a magnetic base, a warning light, a magnetic plate, a photovoltaic panel, a storage battery, and a control box. In use, in dimly lit environments at night, the warning light can be activated via the control box to serve as a warning, making it easily observable and alerting others to avoid the area. During this time, the storage battery continuously consumes its charge. In well-lit environments during the day, the photovoltaic panel utilizes the photovoltaic effect at the semiconductor interface to directly convert solar energy into electrical energy, which is then stored in the storage battery to charge it. This compensates for the nighttime power consumption and enables automatic battery charging. Therefore, there is no need to repeatedly remove and recharge the battery, saving time and effort and offering the advantage of ease of use.
