As someone who regularly commutes by a bicycle, safety is important to Han-Lin, and he's developed his own lighting system with 360° visibility to help him survive Vancouver's dark and rainy days.
This bike light has one yellow headlight, one red tail light, and two amber sidelights which can be used as turn signals.
