In a fishing rod assembly, a motion detection apparatus is mounted in the rod and includes a motion detector to sense any motion or tension in the line imparted to the rod when a fish strikes and to generate an electrical signal in response to such motion, a portable power supply, a light source and circuit control means responsive to the signal produced by the motion sensor to activate the light source, and a plurality of fiber optic elements are arranged for extension through the rod to produce a visual signal along the length of the rod when the light source is activated; and further the circuit means may include an audible alarm which is responsive to the same signal to produce an audible signal when motion is sensed in the rod.
