Using your Blackburn Grid USB Front Light is a breeze. First, charge it using the included USB - C cable and any standard USB port. Once charged, choose the mode that suits your needs. The high solid mode is great for when you need maximum brightness, like riding on dark roads. The constant pulse mode offers a good balance of brightness and run time. The fast strobe mode can make you more visible in traffic, and the eco flash mode is perfect for long rides. To mount the light, use the silicone strap wrap mount which can fit different sizes of bike parts. You can also use the pack and belt loop attachment clip for other mounting options. When it comes to maintenance, keep the light dry and clean. If it gets dirty, gently wipe it with a soft cloth. Avoid exposing it to high - pressure water as it's only protected against low - pressure water jets. With proper use and care, your light will serve you well on all your cycling adventures.
