Abstract
A light guide assembly for an instrument display includes a light housing, a light source and a light guide. The light guide directs light from the light source through an opening in the light housing, and includes at least a first branch and a second branch. A diffuser is disposed above an opening in the light housing. The diffuser includes a bottom surface facing an interior of the light housing and a top surface facing opposite the bottom surface. A dimming feature is disposed on a portion of the top surface of the diffuser, such that the dimming feature reduces a brightness of the portion of the top surface thereby maintaining at least approximately a constant brightness across the diffuser.
