‘LIGHT ON!’ ON THE ADURO 3.0 The USB light for the Aduro 3.0 increases visibility with 8 LEDs and a high position at the rear of the helmet. If you ride your bike in bad weather and when it is dark in the morning or evening, it is a good idea to make sure you are seen early enough in traffic. This light can be optionally attached to the Aduro 3.0 bike helmet by just clipping into place. A rubberised on/off button with splash protection ensures that rain is no problem for the light. This button is also used to switch between the two light modes: continuous illumination or flashing light.
