47. The experts of France and Germany initiated a discussion on how to treat lamps with apparent surfaces in the form of a company logo or other brand-identifying figures (GRE-78-03). The experts from Finland, France, Italy Netherlands, Poland, Spain and UK reported on their national experiences on the subject. GRE noted that, in many countries, specific illuminated advertisement on vehicles was prohibited. However, no clear restrictions existed for lamps which otherwise met the requirements of lighting and light-signalling Regulations, and particularly of Regulation No. 48. GRE was also informed about optional additional lamps that were allowed in some countries for the purposes of road safety, for example, additional direction indicators for trucks in the form of a cyclist. The experts from France and Germany pointed out that they would distribute a questionnaire to GRE experts to solicit detailed information on relevant national practices. In addition, the expert from the Netherlands suggested establishing a task force. GRE agreed to revert to this issue at the next session, based on the outcome of the survey.

48. The expert from SAE informed GRE about the recent changes of the national regulation on motor vehicle lighting and light signalling in Canada and of the associated technical standard document (GRE-79-06 and GRE-79-07). GRE took note of this information.
