As the demand for wireless communication technologies is exponentially increasing, using the visible light electromagnetic spectral region is a logical option. This article provides a general analysis of the IEEE 802.15.7 standard for optical communications using visible light, focusing on the PHY I, intended for outdoor applications. Moreover, the article discusses how the standard's specifications apply to visible light communication use in vehicular networking applications. The article concentrates on the standard's applicability in this domain, and points out the fact that it has not been widely accepted, as most of the VLC developers are focused on decreasing system complexity and implementation costs, rather than complying with the standard's requirements. Furthermore, the article points out the necessity of a novel vehicular applications VLC specific standard, which should focus on the requirements imposed in this specific area.
