• a lamp assembly including:
• a lamp holder having first and second locking mechanisms, wherein the lamp holder is configured to move between an open position and a closed position;
• a light source configured to fit within the lamp holder when the lamp holder is in the closed position;
• an outer bulb detachably attachable to the lamp holder;
• an electrically insulating member configured to be inserted between one or more electrical contacts of the light source;
• and
• a waterproofing device configured to seal around at least a portion of the light source and at least a portion of the electrically insulating member;
• and
• a wiring harness having two or more insulated conductors,
• wherein the first locking mechanism comprises one or more latches, the second locking mechanism comprises one or more receiving slots, and the one or more latches are configured to couple with the one or more receiving slots.

A method of assembling a water-resistant decorative lighting system, the method comprising:

• providing one or more lamp assemblies including:
• a light source;
• a waterproofing device;
• and
• a wiring harness having two or more insulated conductors, the wiring harness configured to electrically connect the one or more lamp assemblies;
• providing an electrically insulating member configured to be inserted between one or more electrical contacts of the light source;
• wrapping at least a portion of the waterproofing device at least partially around a portion of the light source, a portion of the electrically insulating member, and a portion of the wiring harness;
• sealing the waterproofing device;
• and
• providing a lamp holder having a first locking mechanism and a second locking mechanism and being configured to move between an open position and a closed position,
• wherein the light source is configured to fit within the lamp holder when the lamp holder is in the closed position.

The method of 16, further comprising:

• providing an outer bulb comprising a hollow internal cavity;
• causing the lamp holder to be in a closed position within the internal cavity;
• and
• positioning at least a portion of the light source configured to vertically extend above the lamp holder;
• and
• securing the outer bulb to the lamp holder.
