1. A wallbox-mountable electric load control device comprising:
a faceplate assembly couplable to a wallbox;
light sensing circuitry disposable behind the faceplate assembly;
a plurality of backlights;
wherein each of the plurality of backlights associated with a respective one of a plurality of user-selectable input devices;
a plurality of translucent indicia;
wherein each of the plurality of backlights positioned to backlight a respective one of the plurality of translucent indicia; and
control circuitry to:
receive an input indicative of an ambient light level from the light sensor;
determine an ACTIVE input device illumination level based on the received ambient light level data;
determine an INACTIVE input device illumination level based in the received ambient light level data;
receive an input from a user-selected one of the plurality of user-selectable input devices; and
responsive to receipt of the input from the user-selected input device:
cause the backlight associated with the user-selected input device to backlight, at the determined ACTIVE input device illumination level, the translucent indicia associated with the user-selected input device; and
cause the remaining plurality of backlights to backlight, at the determined INACTIVE input device illumination level, the remaining plurality of translucent indicia.
