An LED bulb in a water lamp tube is disclosed. Two light emitting chips in an LED are punched to trim the edges so that two correspondent light emitting pieces are left. A first pin and a second pin are spaced with a distance for positioning a combining plate. The two pins are cut so that the first pin is a smooth post; while a distal end of the second pin is extended to two sides like a T shape. By the aforesaid structure, the second pin of a bulb encloses the first pin of another bulb through 180 degrees; by repeating the process, many bulbs are connected in series so that the bulbs are conductive to each other. Alternatively, the first pin is extended to two sides like a T shape; while a distal end of the second pin is extended to two sides like a T shape. A lead is used to connect two bulbs and two ends of the conductive leads are enclosed by the T shape pins of second bulbs through 180 degrees. As a result, the light emitted is stable and the lifetime will be prolonged.
