Lamp for use in light strings

A lamp for use in light strings comprises:

• an LED lamp;
• a lamp stem connected with the LED lamp;
• and
• a lamp holder in which the lamp stem is arranged;
• wherein the lamp holder is internally provided with a conductive element electrically connected with wires, the LED lamp is connected with the conductive element through the lamp stem, and the conductive element comprises a first conductive element and a second conductive element which are positioned at the left side and the right side in the lamp holder;
• wherein the lower part of the lamp stem is provided with a protruded end, the protruded end is clamped between the two conductive elements, the two lamp bases of the LED lamp are respectively contacted with and conductive with the two conductive elements, and the inner wall of the lamp holder is provided with an elastic element which can enable the two conductive elements to be mutually contacted with and conductive with the current when the lamp is pulled out;
• wherein the elastic element is positioned in the gap among the inner wall of the lamp holder and movable ends of the conductive ends.
