A fishing rod accessory includes a cylindrical coupling that has axially opposed end portions, a bore formed in fluid communication with the end portions, and a stop member positioned therein and extending along an interior surface of the coupling. A switch is partially nested within the coupling and has an axial bore formed therein. Such a switch further has proximal and distal end portions and a rectilinear finger protruding from the proximal end portion. A rectilinear axle has opposed end portions housed within the bore of the switch. A helical spring member is positioned about the axle and is resiliently deformable. The switch further includes a power supply source and an illuminable fixture electrically matable thereto. A fiber optic filament is positioned about the illuminable fixture. A fishing rod extension is removably positional about the switch. The fishing rod extension and the fishing rod intercalate the coupling and the switch therebeneath.
