An oral healthcare personal appliance (10), configured for use with a removable brush head (20) having a first light guide (28), comprises a handle (16), an actuator (14) with a hollow drive shaft (18), a second light guide (36) disposed co-axially between first and second ends of the hollow drive shaft, a rear stop connection adapter (62) coupled to the second ends of the hollow drive shaft and the second light guide, a light source (66) to emit light into the second light guide, and an optional front stop connection adapter (34) coupled to the first ends of the hollow drive shaft and the second light guide. Physically coupling the brush head to the handle enables both (i) a rotation of the brush head via a rotation of the hollow drive shaft and (ii) a transmission of light from the light source through the second light guide and into the first light guide.
