This paper develops a smart underwater communication system using lifi technology which provides protection against ship collisions on the sea. Li-fi (light fidelity) is an emerging technology which uses the visible light spectrum for community. This paper focuses on the safety on sea in which the headlights, which consists of LEDs acting as transmitter, communicate with photo sensors as receiver. White LEDs  used in the head and tail lights can effectively be used for short range communication with the photo detectors. The application is cost effective as LEDs are cheap and simple algorithms are proposed for signal generation and transmission.
