1. A wall-mountable load control device configured to control an intensity of a lighting load, the load control device comprising:
a yoke adapted to be mounted to an electrical wall box; an
enclosure attached to the yoke;
a mounting member attached to the yoke and having an attachment portion configured to extend through an opening of a faceplate;
a potentiometer located within the enclosure and having a shaft configured to extend through an opening in the yoke and the opening of the faceplate;
a rotary knob having a planar surface and a circular sidewall extending from a periphery of the planar surface to form a cavity in the rotary knob, the rotary knob comprising a shaft-attachment member located within the cavity and attached to the shaft of the potentiometer;
a collar attached to the attachment portion of the mounting member and surrounding the shaft of the potentiometer, the collar comprising an opaque portion and a translucent portion; and
at least one light source housed within the enclosure configured to emit light,
wherein the mounting member is configured to conduct the light emitted by the at least one light source to illuminate the translucent portion of the collar.
