Headlamp with backlit side bezel signature image
First Claim
1. A method of illuminating a signature image formed on a trim piece of a vehicle lighting system mounted adjacent a headlamp and having an inner surface illuminated by light from the headlamp and an outer surface visible from outside the vehicle, wherein the trim piece comprises an integrally-molded light transmitting plastic body, wherein the signature image has a foreground region and a background region within a relatively opaque framing area of the trim piece, the method comprising the steps of:
- diverting a portion of the light produced by the headlamp using a refracting element toward the inner surface to backlight the trim piece with an even illumination;
passing the light directed toward one of the background region or the foreground region through a first surface texture that causes a first amount of diffusion of the light transmitted through the trim piece from the illuminated inner surface providing a first brightness in the one region;
passing the light directed toward the other one of the background region or the foreground region through a second surface texture that causes a second amount of diffusion of the light transmitted through the trim piece from the illuminated inner surface providing a second brightness that is greater than the first brightness in the other one of the regions; and
substantially blocking the light directed toward the relatively opaque framing area due to a third surface texture that causes a third amount of light diffusion transmitted through the trim piece from the illuminated inner surface providing a third brightness that is less than the first brightness in the framing area.

Abstract
A lighting system for a vehicle comprises a headlamp light source. A trim piece is mounted adjacent the light source having an inner surface illuminated by light from the light source and an outer surface visible from outside the vehicle. The trim piece comprises a light transmitting plastic body, wherein a signature image is formed on the body having a foreground region and a background region. The foreground region has a corresponding surface characteristic on the inner and outer surfaces within the foreground region different from a corresponding surface characteristic on the inner and outer surfaces within the background region so that more light from the light source is transmitted through the foreground region than through the background region. The outer surface may be fully metalized to provide a pleasing appearance under ambient light conditions.
