Since a few years, the vehicle industry tends to increase the performances of the lights based on led technologies. Nowadays, led systems are used as a standard by motor vehicles manufacturers. Led lights present higher reliability and are more flexible regarding the design or power adjustments. Furthermore, led systems are also very convenient for intensity modulation like in telecommunication fields. We developed a very simple data transmission system based on led that aims to be highly robust at short or medium distances - a few meters up to 15 meters. This visible light communication is dedicated to the cooperation between vehicles and road infrastructures to enhance the security of the traffic. This paper explains the choices and first results on the data transmission performances. In this paper, we present a first prototype of the system we made and experimental results.
