Electronic flashing (illuminated) ice jig is applied for predatory fish fishing. Jig volume has the printed circuit board (2), containing a power supply (3) and an electronic circuit (4) which control the light-emitting diode (1) operation. Jig is overmolded with a special water-tight plastic (5) to form a volumetric shape. Jig has a hook (6) and the eye (7) for fishing line attachment. The eye (7) and the hook (6) are not only used as mechanical components, but also as electrical contacts. Those contacts (7) and (6) are used to detect when jig is placed in water. Placement into water turns on the main controller (9) which is forming the flashes of a light-emitting diode (1). The same contacts are used to charge the jig. A double layer capacitor is used for power supply, which is environmentally friendly, can be quickly charged and small in size. Small size of a jig is the necessary requirement. Switched-mode voltage-to- current converter (10) is used to transfer the power from the power supply (3) to the light- emitting diode (1), thus automatically adapting the converter output voltage to the turn-on voltage of the light-emitting diode.
