  One of the main revolutionary features of 5G networks is the ultra-low
latency that will enable new services such as those for the future smart
vehicles. The 5G technology will be able to support extreme-low latency. Thanks
to new technologies and the wide flexible architecture that integrates new
spectra and access technologies. In particular, Visible Light Communication
(VLC) is envisaged as a very promising technology for vehicular communications,
since the information can flow by using the lights (as traffic-lights and car
lights). This paper describes one of the first experiments on the joint use of
5G and VLC networks to provide real-time information to cars. The applications
span from road safety to emergency alarm.
