Abstract
A light source is positioned to direct light downward from the cover of a conentional analog or electro-optical watch, indicator gauge, a meter panel directional gauge or ornamentation display of an image, logo or design or other similar articles. These articles are illuminated by the source for viewing in low light or in the dark by an illumination switch to activate said element. The light source is preferably an LED and it is small enough so that when it is off, it is virtually invisible.
