The lens set is disposed at a light path downstream side of the light source. The projection film is disposed at a light path downstream side of the lens set. The lens is disposed at a light path downstream side of the projection film. An optical axis of the light source is substantially parallel to an optical axis of the lens set, and an optical axis of the projection lens is not perpendicular to an image plane of the puddle lamp.
