  • Patent number: 4959919
    Abstract: A self-illuminated salt water fishing lure including a hollow lure body which is open to receive salt water in which the body is submerged, and which has a light-transmissive wall; an electric light bulb mounted inside the lure body to produce light visible through the transmissive wall; and a battery, which uses salt water as an electrolyte, mounted inside the lure body for energizing the light bulb. The battery has electrodes with a gap between them which is open to receive salt water when the lure is submerged, but is otherwise empty, so that the battery is activated only during submersion of the lure. One suitable type of battery has a manganese dioxide cathode and an aluminum anode, with an interelectrode gap open at both ends so that sea water can flow into, through, and out of the gap to remove reaction products formed while the battery is activated.
