PURPOSE: A device for controlling a safety light using audio is provided to automatically turn on/off the corresponding safety light by a remote audio calling command, thereby easily turning on/off the safety light. CONSTITUTION: An RF front-end unit(34) receives a wireless audio calling signal transmitted from a remote terminal through an internal antenna. An A/D converter(35) converts the wireless audio calling signal into a digital signal. A DAB(Digital Audio Broadcasting) decoder(36) extracts digital data corresponding to a calling command from the inputted digital signal, and decodes the extracted digital data. A main controller(45) controls turn on/off operations of a safety light, based on a decoded signal of the DAB decoder(36).
