Unipar have now developed the 'Smiley Face' emoticon for their popular Dual Message display. It can alternate between a Smiley Face for drivers below the speed limit and a Sad Face for those over the speed limit. It will also alternate the display to show vehicle speed in real time. Although a new variation to the standard Dual Message display, it may be retro fitted to any existing displays. For more information please contact us and we will be happy to help.
