Fawyobs fishing lights are designed with green light, which is much more water permeable than red, white, and other colors. Even in turbid waters or water layers deeper than 3 meters, it can form a clear band of light. Green lights can accurately activate the aquatic food chain: they first attract plankton as basic bait, and then lure predatory fish such as sea bass, cod, and tuna to fishing sites. The package includes 10 fishing lights, more cost-effective than regular 5-piece sets. It fits diverse needs: attach 1-2 to boat sides/different rig depths for night fishing (3D light zones); keep 3-4 spares for ice fishing (avoids cold-related outages); split for group use. With flexible double-ring buckles, it fixes easily to lines, sinkers, lures—ideal for inshore rock, offshore deep-drop, or freshwater raft fishing to build efficient luring systems quickly. Crafted from corrosion-resistant ABS plastic, this fishing light operates stably in deep seas over 3000 feet. It also endures extreme temperature variations from -30℃ to 60℃, preventing damage caused by seawater leakage and temperature fluctuations—whether for winter ice fishing or tropical sea angling. It is suitable for both saltwater and freshwater environments. Equipped with a high-precision water-sensing chip, it turns on when submerged and off when removed—eliminating idle power waste. Built with a high-efficiency battery, its low-power green LED enables over 180 hours of continuous use, far longer than similar products (several to dozens of hours). No frequent battery changes for all-night, multi-day boat, or long-distance fishing—lets anglers focus on fishing and cuts costs/troubles. Beyond professional luring, its soft, high-penetration light has multiple uses. In aquariums, it highlights ornamental fish colors, attracts plankton (natural forage for small fish), and creates ecological landscapes. For night fishing, it lures fish and illuminates the surrounding area—boosting operational safety and achieving "one light, two uses" practical value.
