Mity Lites are proven effective for swordfish, grouper, snapper, halibut, and other species that are attracted to light. Mity Lites come in a variety of colors including Green, Blue, Purple, Red, and White that strobe in the water. The Blacklight color is a constant on light. When one color is not enough, use the Mardi Gras Mity Lite. Slightly lager than the standard Mity Light, the Mardi Gras rotates through five different glowing colors. Max depth 800 meters water resistant, two batteries included (easy to install). A proven winner in North and South Florida!
