Wind drives a turbine on the light, which powers its LED. It also charges the light's onboard Li-ion battery, storing power from the turbine whenever the bike is in motion, thus eliminating worries about dead batteries.
另一款同樣為成貫設計的風力發電自行車燈，只要騎上單車，風一吹、葉片一轉，風力產生的電能就能讓 LED 燈亮起；更重要的是沒有斷電煩惱，因為騎車時產生的能源，已經轉換儲存到車燈內的鋰電池內。
