Generally, the present invention is directed to medical devices and more particularly to a patient-friendly stethoscope with interactive light emissions. An embodiment of the invention includes a stethoscope which has a pair of binaurals and a transparent acoustical tubing connecting the binaurals to the chestpiece. An optical fiber is located within the transparent acoustical tubing extending from the junction region of the tubing to and within the chestpiece, thereby illuminating the chestpiece, the rim of the diaphragm and bell, and attachments to the chestpiece. The optical fiber has a light source coupled at its proximal end thereby illuminating the transparent acoustical tubing, the chestpiece, and attachments thereto from within.
