Some kids these days can be so keen when it comes to DIY, sometimes more so than adults themselves and this is an excellent example of that. Over at instructables, we just stumbled across this really useful and unique DIY which in my opinion would be greatly appreciated by cyclists who too enjoy abit of DIY for their rides. This 13-year old has designed signal lights which flashes as the cyclist riding the bike turns, that way cars from behind not only sees a bike ahead but also knows the cyclist is about to turn.

Hope the embedded code below works ok for you (might not work 100% in feeds though):
