I am a product designer and am currently working on a bicycle lighting project and would really appreciate your valuable feedback.
In England, turning left on a bicycle is not really a problem as you would just follow the road, but turning right can be an issue as often you would have to change lanes or cut across traffic. Likewise in other parts of the world where you drive on the right, turning left would be the issue. That is why it is so important to use hand signals, so motorists can see your intentions. But how can motorists see your hand signals in the dark?
I have an idea for a bicycle light which would clip onto the sleeve of your clothing; very much like the way an ipod shuffle would clip onto clothes. It would always be on; therefore acting as a safety light as well. If you wanted to turn right, you could put your arm out and then motorists could see your intentions through the flashing light.
Many people have tried to crack the cycling indication market before, but it involves adding expensive and ugly lights to your bike. What if there was something as easy as the above, that just clips onto your sleeve- no need for bike modifications and probably less than a £10 spend.
This in mind, any answers to the following questions would be great:
Do you find it difficult to indicate in the dark? Do you think an idea like this would improve bicycle safety? Would this be something that you would buy?
