The lighting set, consisting of the AURA 60 USB headlight and the SIGMA® INFINITY rear light, is your reliable companion for sporty training on the road bike or gravel bike. The USB lights have legal approval StVZO and RAI Hallmark Bicycle Lighting and you can attach them to the bike very easily without tools. With a beam of around 70 meters and 60 Lux, the AURA 60 USB excellently illuminates streets and roads and, with the Light Guide, provides improved visibility from the side. The extremely slim SIGMA® INFINITY taillight impresses with a burn time of up to 16 hours. The two-stage battery indicator reliably provides information about the state of charge and reminds you to charge in time. The control knob of your AURA 60 USB is also a charge indicator and indicates the charging state of the battery. Below 70% battery capacity, the LED in the button lights up green, below 30% red.
