- PROBLEM - Riding in the dark is scary
Goals
- Increased safety - higher rider visibility
- Increased safety / allow night riding - forward navigation lighting
- System is easy to maintain - wirelessly update/develop (OTA updates)
- System is water resistant - lights are IP rated, hardware is sealed, no need to open enclosure
- Limit manual actions required - implement passively triggered ‘smart’ systems
- No additional batteries (single charge port) - power from main battery
- Ability to develop alternative lighting modes - utilize individually addressable LEDs
- SOLUTION - Develop front and rear smart LED strips
