Our range of lights at 99 Bikes consists of USB and battery-operated options, including the brands Raveman, Knog, Lezyne, and more. There's two reasons you need lights, one, to see, and two, to be seen! We have both front and rear lights, and even handy light sets. USB lights tend to weigh less and prove more cost-effective over time by negating the need for replacing the battery. Those with batteries may be the preferred option for those not in favour of needing to recharge every once in a while!
