Using your Topeak helmet light is a breeze. First, use the rubber strap to attach the light to your helmet or road bike dropbar. There's no need for any tools, so it's quick and easy. To turn it on, find the control button on the light. It has 4 different modes: high, middle, low, and a mode where the front is on middle and the rear is blinking. Just press the button to cycle through these modes. When the battery runs low, you'll see the low battery indicator. To recharge it, simply connect the micro - USB cable to your computer. It takes about 2 hours to fully charge. As for maintenance, since it's waterproof (IPX 6), you don't have to worry too much about light rain. But try to avoid submerging it in water for a long time. Keep it clean by wiping it with a soft, dry cloth regularly. Store it in a cool, dry place when not in use.
