These products supersede the conventional fishing rod-mounted chemiluminescent lights used to reveal when fish nibble at the bait. They comprise a miniaturized lithium battery and LED, and can be used four times longer than chemiluminescent lights. And since they are re-usable rather than thrown away after use, they are much more environment-friendly. The lights are attached to a urethane pad and can be fitted to fishing rods of almost any thickness.
