Helmet headlamp assemblies and related methods

A headlamp assembly for attachment to a helmet, the headlamp assembly comprising:

• a base plate comprising a periphery, the periphery defining a first end and an opposite second end, wherein the base plate defines a longitudinal axis extending between the first end and the second end and a transverse axis perpendicular to the longitudinal axis, wherein the periphery of the base plate conforms to a contour of the helmet;
• a first plane containing the longitudinal axis and the transverse axis, a second plane extending perpendicularly to the first plane and containing the longitudinal axis, and a third plane extending perpendicularly to the first and second planes;
• a housing releasably coupled with the base plate, the housing defining a top side spaced apart from the base plate and a front side extending between the top side and the first end of the base plate;
• a first light source coupled with the housing, the first light source having a first facing direction that is perpendicular to the first plane;
• a second light source disposed between the housing and the base plate, the second light source having a second facing direction that is perpendicular to the third plane;
• and
• a member removably coupled with the housing and disposed over the first light source.

A method of attaching a headlamp assembly to a helmet, the method comprising:

• providing a headlamp assembly comprising:
• a base plate comprising a first end and an opposite second end, wherein the base plate defines a longitudinal axis extending between the first end and the second end and a transverse axis perpendicular to the longitudinal axis;
• a first plane containing the longitudinal axis and the transverse axis, a second plane extending perpendicularly to the first plane and containing the longitudinal axis, and a third plane extending perpendicularly to the first and second planes;
• a housing, the housing defining a top side and a front side, the top side comprising an internal surface facing the base plate and an external surface opposite the internal surface, the front side extending between the top side and the first end of the base plate;
• and
• a first light source coupled with the housing, the first light source having a first facing direction that is perpendicular to the first plane;
• attaching the base plate to the helmet with the first end of the base plate located at a front portion of the helmet;
• coupling a second light source with an interior surface of the housing;
• and
• coupling the housing with the base plate such that the second light source has a second facing direction that is perpendicular to the third plane.
