Visible light communication (VLC) has attracted attention as a candidate connectivity solution for future intelligent transportation systems by leveraging existing vehicle headlights and taillights as wireless transmitters. In this paper, we present an experimental investigation of an MISO vehicular VLC system in which the two headlights of a vehicle simultaneously transmit the same safety messages to another vehicle with a single photode-tector receiver installed at the back of the vehicle. It is expected that the two transmission paths will provide link diversity to improve the communication reliability. Our experimental findings demonstrate that error-free communication using the OOK scheme is possible beyond a 40 m transmission range when the vehicles are in perfect alignment. In our mobility tests, where both vehicles were moving at a speed of approximately 20 km/h with a separation distance of 8–10 m between the vehicles, we achieved an average PDR of 89.58% for 2 × 1 MISO configuration, which was reduced to 81.05% when a single headlight was used for transmission in SISO configuration.
