11 . The portable lighting device of claim 10 , wherein the rear portion of the housing includes at least one magnet configured to removably affix the portable lighting device to a support surface, and wherein the rear portion also includes a removable cover that encloses both of the charging port and the at least one magnet.
12 . A portable lighting device that can be removably affixed to an article of clothing worn by a user, the lighting device comprising:
a housing including: (i) a top wall, (ii) a bottom wall, (iii) a front portion, (iv) opposed side portions extending between the top and bottom walls, and (v) an electronics package including a power source;
a flexible LED lighting element operably connected to the power source, said lighting element including a pivotable coupling support extending from a central portion of said lighting element, wherein the coupling support is pivotably coupled to the front portion of the housing;
an attachment means coupled to the housing, wherein the attachment means is adapted to be removably affixed to an article of clothing worn by a user of the portable, wearable lighting device;
wherein in a retracted position, a first end portion of said lighting element is received in a first securement recess in a first side portion of the housing, and a second end portion of said lighting element is received in a second securement recess in a second side portion of the housing, to collectively define a compact state S C ; and,
wherein said lighting element and the pivotable coupling support provide the lighting device with two degrees of freedom of adjustment during operation of the lighting device.
13 . The portable lighting device of claim 12 , wherein in the compact state S C , an intermediate portion of said lighting element is received within a frontal securement recess formed in the front portion of the housing.
14 . The portable lighting device of claim 13 , wherein in the compact state S C , said lighting element has a substantially U-shaped configuration when observed in top view of the portable, wearable lighting device.
