Perfect for daytime or nighttime use, the Nite Brite lighted float from Thill triples as lighted float, slip float, and fixed float to cover all your angling needs. The Nite Brite's unique E. L. light glows 20 times brighter than, and lasts twice as long as, most other lighting systems. Just pop the cap, push the battery top, and you've got bright light! Long-lasting lithium battery included. Through-the-center slider hole construction offers tangle-free slip-bobbering.
