Dial plate with diffuse lighting

A motor vehicle, comprising:

• a dial plate including a central portion and a curved peripheral portion disposed radially away from the central portion;
• an outer radial portion of the curved peripheral portion and an inner radial portion of the curved peripheral portion;
• a light-guide disposed radially inward of the curved peripheral portion;
• the light-guide receiving light from at least one light source, the light-guide including a light exiting portion configured to illuminate substantially the entirety of the curved peripheral portion, including the inner radial portion and the outer radial portion, such that the inner radial portion and the outer radial portion have a constant brightness when viewed from an axial direction.

A motor vehicle, comprising:

• a dial plate including a central portion and a curved peripheral portion disposed radially away from the central portion;
• a light-guide disposed radially inward of the curved peripheral portion, the light-guide receiving light from at least one light source and being configured to direct light towards the curved peripheral portion;
• the light-guide having a base portion and a top portion;
• the base portion being disposed adjacent to a first side of the central portion with respect to an axial direction;
• the top portion extending a first axial height above the central portion;
• the curved peripheral portion comprising an inner radial portion that is disposed adjacent to the first side of the central portion with respect to the axial direction, and an outer radial portion;
• and
• the light-guide is configured such that light exiting the light-guide illuminates the curved peripheral portion over an illuminated region, the illuminated region having a second axial height above the central portion, wherein the second axial height is greater than the first axial height.
