The Thill Nite Brite Replacement Battery powers the versatile Thill Nite Brite float, which functions as a lighted, slip, and fixed float all in one. This battery supports a bright, long-lasting glow—20 times brighter and twice as enduring as most lighted bobbers—available in red, green, or yellow for easy night fishing and float identification. Designed for quick installation, it ensures uninterrupted performance from day to night without rig changes.
