A head lamp device for automobiles has a light source and a cover member arranged in front of the light source. The light source is comprised of a transparent hard resin plate curved outwardly at its central part, and a transparent soft resin sheet intimately in contact with a rear surface of the transparent hard resin plate with a peripheral edge of the transparent soft resin sheet attached fluid tight to a peripheral edge of the transparent hard resin plate. The transparent hard resin plate has a pipe through which a colored solution is supplied into and removed from a space formed between the transparent hard resin plate and the transparent soft resin sheet.
