Product test
Lab tests are conducted to approve components: batteries, battery life, UV resistance, durability, etc. The final product is then tested to simulate the durability of the assembly over time. The light is fitted to a test bike to reproduce the vibrations of cycling on a road for several thousand cycles.

Maintenance tips
Remove the electronic component from the VIOO before cleaning the soft part with clean water and soap.
