This paper introduces visible light communication (VLC) for inexpensive vehicle-to-vehicle messaging (V2V) using off the shelf LEDs and photo diodes. VLC is a cost effective method to integrate with intelligent transport systems (ITS) for road safety applications. Light from the brake lamps of a vehicle can be used to transmit messages for emergency hard brake, so that the following vehicle can take precautionary measures to avoid accidents. A prototype V2V communication system is designed that has low complexity and high reliability. Experimental evaluation of the prototype shows that the system can detect hard brakes from a distance of 20m and can provide early warning to drivers following at the speeds upto 80 km/h, reducing the chances of road accidents.
