The Droplet Traffic Light concept looks like your standard traffic light, but it makes good use of the back of itself. The inactive side of the traffic light is used to display news blurbs and weather conditions. Sounds like something to do for folks who are sitting there waiting for the light to turn green. Of course, the bad news is that it probably isn’t good for safety since drivers should really be paying attention to the traffic lights, instead of reading the news. Still, if it kills time and eases the pain of sitting in a traffic jam, that’s not too bad.
