Abstract (en)

In a vehicle lamp having a light source (1) and which is capable of producing a coloured light, a grid member (5) is incorporated between a filter (4) and a light-transmitting cover (3), the elements (6) of the grid member presenting surfaces (6a), (6b), (6c) and (6d) which are out of line with the direction (8) of the light, before it passes through the filter such that the grid member reflects external light entering the lamp to a large degree thereby to impede such external light from impinging on the light source or filter, the coloured light being directed by an optical pattern on the filter through the openings (7) in the grid when the lamp is operating.
