DIY Bicycle Turn Signal

Many of us use bikes for commuting and leisure, and many of us suffer from long and dark winters as well! If that’s the case, you probably have a pair of bright front & rear lights, which make spotting you much easier for drivers and other road users, making cycling much safer. There is however another issue when riding on the road: turn signals! There is a hand signal convention, but I have the feeling that many drivers don’t understand it, or maybe it’s dark, or you’re not confident to take your hand out of the handlebar. This motivated my friend and I to build an electronic turn signal, which will be placed close to the rear light with a control switch in the handlebar.”
