A lamp unit has a reflector ( 10 ) having a reflector surface ( 12 ) with an inverted U-shaped aperture ( 14 ) formed therein and extending through said reflector to an opposite surface ( 16 ). The inverted U-shaped aperture thereby has a bight ( 18 ) uppermost with a pair of channels ( 20, 22 ) depending therefrom. A light-shield ( 24 ) comprises a cup-shaped member ( 26 ) having an arm ( 28 ) projecting therefrom. The arm ( 28 ) has a distal end ( 30 ) formed to provide a pair of nibs ( 32, 34 ) for engaging and penetrating the channels ( 20, 22 ) of the inverted U-shaped aperture ( 14 ). The nibs ( 32, 34 ) have their ends ( 36, 38 ) deformed to fix the position of the light-shield ( 24 ) relative to the reflector ( 10 ).
