A question was raised at a previous meeting by Senator Terry Brennan, who is not present, about lighting on motorways. If I am interpreting him correctly, he stated there was more lighting on motorways than anywhere else in the country. The impression one got from his comments was that the lighting appeared to be on 24 hours a day and that there was a potential saving in that respect without risking health and safety. Mr. Barry might address that point.
