Abstract

A system and method for illuminating individual animal cages secured in a multiple cage rack is described. A first lighting system makes use of LEDs secured on the frame of a multiple cage rack; or attached to or disposed in each individual cage. A second lighting system utilizes fiber optic cables connected to or adjacent each individual cage or disposed within. Clear observation of all animals at will is economically provided without interference with normal cleaning and sterilizing procedures, utilizing the virtually maintenance free lighting system.
