• a shell including
• a first end,
• a second end opposite the first end,
• a through hole extending through the first and second ends, and
• a first plurality of grooves formed in an inner surface of the shell;
• a light emitting body having a first end and a second end opposite the first end, wherein the first end of the light emitting body is positioned within the through hole in the shell with the second end of the light emitting body extending from the second end of the shell, and wherein the shell is configured such that the second end of the light emitting body is installed through the first end of the shell;
• a plurality of pins coupled to the first end of the light emitting body;
• a plurality of wires corresponding and coupled to the plurality of pins;
• a column having a first end and an opposite second end, wherein the column is positioned adjacent the first end of the light emitting body and between the plurality of pins, wherein the column has a second plurality of grooves formed in an outer surface of the column, wherein each groove of the second plurality of grooves extends from the first end to the second end of the column and is configured to receive one of the pins of the plurality of pins and separate the pins of the plurality of pins from one another, and wherein the first plurality of grooves and the second plurality of grooves are aligned to form tracks configured to receive the plurality of pins coupled to the light emitting body;
• and
• a tail plug configured to be inserted into the shell independently of the column, wherein the tail plug is positioned adjacent the first end of the column opposite the light emitting body, the tail plug having a third plurality of grooves, wherein each groove of the plurality of grooves is configured to receive one of the wires of the plurality of wires and separate the wires of the plurality of wires from one another, and wherein the third plurality of grooves is aligned with both the first plurality of grooves and the second plurality of grooves to form tracks, and wherein the tail plug has a diameter greater than a diameter of the through hole.

A decorative lamp, comprising:

• a shell including a first end, a second end opposite the first end, and a through hole extending through the first and second ends, wherein an outer side wall of the shell includes at least two stepped structures;
• a light emitting body positioned in the through hole of the shell, wherein a first portion of the light emitting body extends into the through hole, and a second portion of the light emitting body extends out of the shell;
• a plurality of wires configured to couple the light emitting body to a power supply, wherein the wires are at least partially received in a first plurality of grooves formed on an inner side of the shell;
• and
• a tail plug,
• wherein the wires are at least partially received in a second plurality of grooves formed in the tail plug, wherein the tail plug includes a diameter greater than or equal to a diameter of the through hole and abuts against an internal wall within the shell,
• wherein the tail plug includes a circumferential groove, and an inner side wall of the shell includes a ridge, and
• wherein the ridge is configured to engage the circumferential groove to secure the tail plug to the shell.
