1. A catheter, tube, or instrument comprising:
a tube having light-transmissive walls with a distal portion configured for insertion into a patient and a proximal portion that remains external to the patient, the tube having at least one lumen for fluidic transport;
a tip at the distal portion for insertion of the tube into a patient at a skin insertion site;
a light source configured and embedded within the wall of the tube to emit safe, antimicrobial light throughout the light-transmissive walls to illuminate sites of microorganism colonization and potential sources of infection at the skin insertion site, within the lumen, and on an outer surface of the tube; and
wherein the tube is made from a material that transmits light through an inner surface and the outer surfaces of the tube, and further transmits light longitudinally down an axis of the tube.
