Wireless communication has become such a basic utility in our daily lives that it has become a fundamental part of our existence, and it employs the radio spectrum to convey data. Capacity, efficiency, availability, and security are among concerns that arise while using the radio spectrum. Wi-Fi use has also been shown to harm the ecology, including plants and animals. The notion of the light fidelity (Li-Fi) technology was born out of the flaws in Wi-Fi technology. Li-Fi is a sophisticated technology. This initiative is focused on vehicle-to-vehicle communication to prevent accidents on the road. Ultrasonic sensor, LDR sensor, solar panel sensor, OLED display, and Li-Fi transmitter and receiver are among the devices we utilize. If the front car experiences an abnormal situation, the vehicle in the rear will be notified and will come to a complete stop. Due to its low noise ratio, it is one of the most well-suited communication media. We use the Arduino UNO to program a laser to send binary bits with its specific ASCII code to the solar panel which then gives a character based on what binary numbers has been sent.
