Using your Fusion Drive Pro 600+ Front bike light is easy. First, charge it via the waterproof USB - C port (you'll need to get your own cable). Once charged, choose from the six output modes to suit your riding conditions. The Daytime Flash is great for daytime visibility. The intelligent Power Indicator will show you how much battery is left. You can mount it in different ways with the optional GoPro mount. Remember, the original Infinite Light Power Pack won't work with this light, but the Infinite Light Power Pack+ (coming soon) will. When it comes to maintenance, keep it dry and clean. After riding in wet conditions, dry it thoroughly. Also, don't expose it to extreme temperatures. With proper care, your light will serve you well on many rides.
