How useful do you think a brake light would be on bicycles?
I am thinking in particular it could be useful for commuters/riders in urban environments, in making the traffic more aware of the cyclists intentions. Although it could prove useful for group mountain biking at night.
I'm thinking about producing it for one of my projects at uni this year, but haven't really decided on if it is a product aimed at a problem that doesn't really exist or if it could be useful.
It would most likely be something that works similarly to the "lucidbrake" light, so is activated based on an accelerometer detecting deceleration rather than brake cable movement, so it would work on any bike, in any position.
I appreciate any thoughts or criticism.
