The Rapala Lighted Marker Buoy is a water activated marker buoy from Rapala that shines bright the moment it hits the water. It features an On/Off switch inside for daytime use. Two super bright LED bulbs work hard with 60 hours of run time and two replaceable AA batteries (not included). The balanced, compact low-profile shape reduces unncessary line release in wavy conditions. A 50 foot cord with 6 oz. flexible weight to keeps it in place.
