BackLit

Turn signal/road communication device

The project was developed over the span of 3 months as part of the Hemda’s Makers course.

The inspiration for the project came from the question: If every vehicle has a way to communicate with all the other vehicles, then how come bikers don’t have a way to do the same?

When the question wasn’t answered by a google search, we decided to answer it ourselves. And this is where BackLit comes in.

BackLit is a real-time voice-controlled detachable turn signal/road communication device, meant primarily for cyclists and their safety while riding.
