Using the KTV Drive Pro 300+ front bike light is a breeze. First, charge it using a USB - C charger (cable not included). You can switch between the six output modes easily according to your needs, like using the Daytime Flash mode during the day for better visibility. When riding, make sure the light is securely attached to your bike. As for maintenance, since it's waterproof, you can clean it with water. But avoid using harsh chemicals. Also, don't forget that the original Infinite Light Power Pack won't work with this light, so wait for the upcoming Lezyne Infinite Power Pack+ if you want to extend the runtime.
