Bright Block is a bike light with a suite of sensors taking data to make cycling safer in cities! We map pollution and near misses with cars to highlight gaps in infrastructure and tell the story of how infrastructure shapes safety.

The Device Directly Measures:
- PM 2.5 [μg/m³]
- Near Misses with Cars

We're running a pilot in SF staring early May. After that stay tuned for our larger launch! In the meantime - we are selling merch.
