A fish bite indicator that provides an indication of the fishing line being pulled from the reel during night-time or low light conditions is described. The fish bite indicator has a light source attachment feature that is configured on the spinning portion of the reel, such as the reel top. When a fish bites the lines and pulls the fishing line from the reel, the reel spins and the spinning light is clearly visible to a nearby angler. The fish bite indicator is detachably attachable to a reel in some embodiments. In other embodiments, the fish bite indicator has a body forming an enclosure around the light source with one or more openings in the body. The light projected from the openings creates a repetitive flash when the reel spins. A glow-stick type or LED light may be used with the fish bite indicator described.
