A light-emitting wand is configured for selective cooperative coupling with a handset. The wand extends between longitudinally opposed wand-body proximal and distal ends, the distal end being configured to retain a light-emitting element. Extending in mutual parallel alignment between the proximal and distal ends are electrically-conductive first and second core members. Each core member has, at the distal end, a light-source contact configured for electrical contact with a respective pole of the light-emitting element and, at the proximal end, a power-source contact configured for electrical contact with a respective terminal of an electrical-power source. The core members are maintained in mutual electrical isolation and overmolded with an electrically-insulative material through which the power-source contacts are exposed in order to enable selective electrical connection with electrical-power source terminals. In addition to carrying electrical current, the core members serve as heat sinks to dissipate th
