FUTURE WORK & CONCLUSION

Future Work

      • Communication: Explore alternative protocols (Wi-Fi …)
      • Waterproof: Rainy day
      • Adaptive Brightness: EL panels automatically adjusted according to Environment
      • Detachable Equipment: Modular design for easy transfer between jackets/bikes

Conclusion

      • Building on our existing knowledge and expanding upon it, we can improve the safety of low-light condition cyclists.
