Abstract: A light-transmitting plastics shield 1 is provided with distance pieces 5 for attachment to the lens 2 of a headlamp, each distance piece comprising a male part 6 and a female part 7, the male part being ultrasonically welded to the shield and comprising a cylindrical head 12 supported between spaced walls 10, 11, the female part 7 comprising a disc-shaped base 14 carrying a socket portion 16, and the base being secured to the lens by an adhesive foam pad 15. The heads 12 are received within the socket portions 16 and are mounted with their axes parallel to allow the shield to be pivoted away from the lens for cleaning. The heads are also capable of axial movement within the sockets to allow for thermal expansion of the shield.
