If you wish to do so, please comment before purchasing. With 12 LEDs, it has considerable light output, providing more than enough effect for fishing. Also, the black light itself has been modified to be used as a line breaker. This is a cost-effective item that serves two purposes. ※ Uses 3 AAA batteries. Batteries are not included. ① Black Light Do you use a headlamp to charge glow-in-the-dark lures, which are often used in Mebaru, Ajing, and Egi fishing? You'll find that the light from a headlamp has a low amount of ultraviolet light, which shortens the duration of the glow and reduces the amount of light emitted. In comparison, a black light has a lot of ultraviolet light, which can significantly increase the amount of light emitted and its duration. The glow fades over time and needs to be repeated many times, so we recommend using a black light that is easy to maintain. ② Line Breaker When you get snagged and can't avoid it, you may need to cut the line. Many people cut the line by pulling on the rod or wrapping the line around their hand, but pulling on the rod can put a lot of stress on the rod and reel, which can lead to damage. Also, wrapping the line around your hand can cut your hand. When you decide to cut the line due to a snag, using a dedicated tool (line breaker) can reduce these risks to almost zero. In addition, it can also be used to tighten the line when connecting PE line and leader to increase the knot strength. I have many other homemade useful tools for sale.
