Using this Topeak front light is a breeze. First, use the rubber strap to mount it on your aero or round fork blade. You don't need any tools for this, so it's quick and easy. Then, charge the light using the included micro - USB cable. It takes about 2 hours to fully charge. Once charged, you can switch between the 4 different lighting modes. The high - beam mode is great for when you need maximum visibility, while the low - beam mode saves battery. The blinking and pulse modes are good for getting attention. When the battery is low, the low - battery indicator will let you know. To keep your light in good condition, avoid exposing it to extreme temperatures and moisture. Clean it gently with a soft cloth when it gets dirty. And that's it! Enjoy your well - lit rides.
