The present invention relates to an automotive grill assembly (10) in form of an elongate illumination assembly (20) comprising a number of elongate grill elements (11) and a grill surround (12), with the leading edge of each grill element (11) being suited to be illuminated for highlighting the repeating wave pattern thereof, further comprising: an elongate housing (23), printed circuit boards (PCBs) (22) featuring light emitting diodes, an elongate light guide (24) and an elongate lens (21) with a repeating wave pattern profile, wherein the light guide (24) has a first end (24a) having a first light receiving surface (24b), a second end (24c) having a second light receiving surface (24d), and a light emitting surface (24e) viewable to an external viewer of the illumination assembly (20) through the lens (21),wherein a PCB (22) is located at both the first end (24a) and the second end (24c) of the light guide (24), wherein an LED light source located on each PCB (22) is positioned adjacent to the first light receiving surface (24b) and the second light receiving surface (24d) of the light guide (24), which is configured to allow light to enter the light guide (24) through the light receiving surfaces (24b, 24c), wherein the light guide (24) is adapted to be substantially transparent and without any visible discrete optic features in an un-lit state while being diffusive in a lit-state, such that when lit, light exits the light guide (24) at light emitting surface (24e) with substantially uniform luminous intensity across the surface, wherein the light guide (24) has a front region (24f) adjacent the light emitting surface (24e) and a rear region (24g) furthest from the light emitting surface (24e) with the rear region (24g) having a larger sectional thickness than the front region (24f), and wherein the light emitting surface (24e) has the same repeating wave profile as the leading edge of the lens (21), with the front region (24f) of the light guide (24) also having this repeating wave profile and the rear section (24g) of the light guide (24) also having a repeating wave profile but with a smaller amplitude resulting in a straighter profile.
