Abstract: A fishing rod includes one or more signal devices in a portion thereof and a power system that is connected to and activates the one or more signal devices when the fishing rod is flexed by a fish. The connection between the one or more signal devices and a power source includes a control switch and an activation switch that includes an electrically conductive pin mounted on the fishing rod and an electrically conductive coil spring surrounding the electrically conductive pin. The circuit between the one or more signal devices and the power is completed when the control switch is in the “on” condition and the electrically conductive pin and the electrically conductive coil of the activation switch are in electrical contact with each other. A kit may be used to retrofit an existing fishing rod.
