Li-Fi is the latest technology of the world. The aim of this paper is to provide an idea to reduce road accidents by communication between vehicles using Li-Fi technology. Ultrasonic sensor can be used to measure the vibration level in vehicle and to measure the distance of front vehicle. The gas sensor can be used to measure the liquor level of the driver. If any abnormal condition arises in front of the vehicle, vehicle will stop immediately. Li-Fi is connected to UART function to the microcontroller. Serial data communication and Parallel data communication are two ways of communication in UART for communication between two vehicles. Serial data communication is the main function of UART. Light fidelity is an innovative technology based on data transmission using beam of light as a medium. It uses visible light communication which eliminate the entanglement of cable communication. Li-Fi has proven to be safe, efficient and can transmit data at very high speed. A communication system is also presented in this paper. In this communication system information is transmitted from transmitter to receiver for controlling the speed of two motors using light beam as medium.
