DVN Workshops are increasingly providing a venue and forum for crucial discussions about the world's lighting regulatory issues. This trend got started in early 2012 with a talk on LED contributions to roadway safety. The enthusiastic participation in that discussion showed the need and desire for more regulation-centred talks. In July of that same year at Tokyo, such a talk was held looking at how the approach to global harmonisation of lighting and light-signalling regulation needs to be changed to encourage the introduction of new technologies and to support manufacturers to be competitive without compromising safety. Then at the 2013 US Workshop near Detroit, discussion panellists were asked if it is time for a global initiative to harmonise the technical requirements of lighting and light signalling and, if so, where they saw the biggest opportunities. This same topic was on the docket a few months later at the China DVN Workshop at Shanghai, with added discussion on constraints and methods surrounding harmonisation.
