Abstract
A gauge assembly that is illuminable by a light source is provided. The gauge assembly may include a dial face having a translucent portion forming at least a perimeter of the dial face and a cover disposed behind the dial. The cover may define a plurality of graduated lines, at least one of the graduated lines having a first portion extending behind the translucent portion and a second portion extending outward from the perimeter of the dial face. The first portion may be visible through the translucent portion when the gauge is illuminated by the light source and obscured by the translucent portion when the gauge is not illuminated by the light source.
