Flush-mount LED housing

A light strand comprising:

• a first housing having a first end and a second end opposite the first end, wherein:
• the second end of the first housing comprises a first cylindrical sidewall that forms a first recess in the first housing, the first cylindrical sidewall comprising a first helical ridge;
• a first light source electrically coupled with the first housing, wherein:
• light from the first light source is configured to be emitted from the first housing at the first end of the first housing;
• and
• the first light source comprises a white light emitting diode and a red, green, and blue light emitting diode;
• a first cap configured to be removeably coupled with the second end of the first housing, wherein:
• the first cap comprises a first cylindrical base and one or more walls that form a first opening, the first cylindrical base comprising a second cylindrical sidewall configured to fit within the first recess in the first housing, the second cylindrical sidewall comprising a second helical ridge configured to mate with the first helical ridge;
• and
• the first cap is configured to remain fixed with respect to the first housing while coupled with the first housing;
• a first flange fixedly coupled with the first housing at the second end of the first housing, wherein:
• the first flange comprises one or more walls that form a first cavity configured to receive a first fastener to secure the first housing to a surface;
• and
• the first cavity is in the first flange;
• a second flange fixedly coupled with the first housing at the second end of the first housing, wherein:
• the second flange comprises one or more walls that form a second cavity configured to receive a second fastener to secure the first housing to the surface;
• and
• the second cavity is in the second flange;
• a second housing having a first end and a second end opposite the first end, wherein:
• the second end of the second housing comprises a cylindrical sidewall that forms a recess in the second housing;
• a second light source electrically coupled with the second housing, wherein:
• light from the second light source is configured to be emitted from the second housing at the first end of the second housing;
• and
• the first light source and the second light source are configured to be individually addressable;
• a second cap configured to be removeably coupled with the second end of the second housing, wherein:
• the second cap comprises a second cylindrical base and one or more walls that form a second opening, the second cylindrical base configured to fit within the recess in the second housing;
• and
• the second cap is configured to remain fixed with respect to the second housing while coupled with the second housing;
• a third flange fixedly coupled with the second housing at the second end of the second housing, wherein:
• the third flange comprises one or more walls that form a third cavity configured to receive a third fastener to secure the second housing to the surface;
• and
• the third cavity is in the third flange;
• and
• a fourth flange fixedly coupled with the second housing at the second end of the second housing, wherein:
• the fourth flange comprises one or more walls that form a fourth cavity configured to receive a fourth fastener to secure the second housing to the surface;
• and
• the fourth cavity is in the fourth flange
• a first cable connecting the first housing with the second housing, wherein:
• the first opening is configured to be aligned parallel with the second opening while the first cap is removeably coupled with the first housing, the second cap is removeably coupled with the second housing, and the first cable is fully extended between the first housing and the second housing.
