I was amused to see an item about bike turn signals in a blog called cleantechnica.com, the "#1 cleantech or clean energy site in the United States." The author asks the question, "Why didn’t someone come up with this a long time ago?! Turn signals for bicyclists would be very useful and could go a long way towards reducing bicycle-vehicle collisions." He then quotes from and points to a longer piece on some other site that gives more details about a do-it-yourself solution to this perceived problem. The inventor asserts that, "unfortunately, few people know hand signals anymore, so [he] decided to make his own wearable turn signals that he could put on his arms and turn on by lifting his arm up from his side." These signals "use a mercury tilt switch and some electroluminescent (EL) panels that light up to show big bright arrows every time he lifts up the arm that corresponds with the direction he wants to move."
This CleanTechnica site lets you embed an entire page (more or less) in your blog entry. So here is the page:
