An illuminated tweezer assembly comprising a housing having an opening with internal threads; a lamp disposed within the housing and adjacent the opening; a battery disposed within the housing for providing electrical power to the lamp; an elongate shaft that is optically-transmissive, the elongate shaft comprising: a shaft portion having a proximal end and a distal end; external threads disposed adjacent the proximal end of the shaft portion, the external threads matching the internal threads of the opening in the housing; and a recessed section disposed in the shaft portion between the proximal end and the distal end of the shaft portion; and characterized in that a flexible arm comprises: an arched central section having a proximal end and a distal end; and a clamp structure disposed at the proximal end of the arched central section, the clamp structure having opposing jaws that are operable to flex outward to snap in place around opposing sides of the recessed section of the elongate shaft, thereby securing the flexible arm to the elongate shaft such that the distal end of the arched central section is disposed proximate to but not contacting the distal end of the shaft portion, wherein as a pressing force is applied to the arched central section of the flexible arm, the distal end of the arched central section is operable to move into contact with the distal end of the shaft portion. a housing having an opening with internal threads; a lamp disposed within the housing and adjacent the opening; a battery disposed within the housing for providing electrical power to the lamp; an elongate shaft that is optically-transmissive, the elongate shaft comprising: a shaft portion having a proximal end and a distal end; external threads disposed adjacent the proximal end of the shaft portion, the external threads matching the internal threads of the opening in the housing; and a recessed section disposed in the shaft portion between the proximal end and the distal end of the shaft portion; and characterized in that a flexible arm comprises: an arched central section having a proximal end and a distal end; and a clamp structure disposed at the proximal end of the arched central section, the clamp structure having opposing jaws that are operable to flex outward to snap in place around opposing sides of the recessed section of the elongate shaft, thereby securing the flexible arm to the elongate shaft such that the distal end of the arched central section is disposed proximate to but not contacting the distal end of the shaft portion, a shaft portion having a proximal end and a distal end; external threads disposed adjacent the proximal end of the shaft portion, the external threads matching the internal threads of the opening in the housing; and a recessed section disposed in the shaft portion between the proximal end and the distal end of the shaft portion; and characterized in that a flexible arm comprises: an arched central section having a proximal end and a distal end; and a clamp structure disposed at the proximal end of the arched central section, the clamp structure having opposing jaws that are operable to flex outward to snap in place around opposing sides of the recessed section of the elongate shaft, thereby securing the flexible arm to the elongate shaft such that the distal end of the arched central section is disposed proximate to but not contacting the distal end of the shaft portion, an arched central section having a proximal end and a distal end; and a clamp structure disposed at the proximal end of the arched central section, the clamp structure having opposing jaws that are operable to flex outward to snap in place around opposing sides of the recessed section of the elongate shaft, thereby securing the flexible arm to the elongate shaft such that the distal end of the arched central section is disposed proximate to but not contacting the distal end of the shaft portion, wherein as a pressing force is applied to the arched central section of the flexible arm, the distal end of the arched central section is operable to move into contact with the distal end of the shaft portion.
