Summary:Feeding device for a geometrically closed lightguide (1) of the signal lamps of motor vehicles placed on both sides of the vehicle comprising a light feeder (4) and a geometrically closed lightguide (1). The two parts are joined and form a single plastic molding. A prism-shaped cavity (9) with total internal light reflection for a uniform light distribution at both sides of the enclosed lightguide (1) is formed at the site of their joint. A semi-transparent insert (16) is inserted in the prism-shaped cavity (9), made of material with a precise ratio of transparent and cloudy components to control the amount of unwanted light arising on the planar surfaces (10;11) of the prism-shaped cavity (9) with total internal light reflection.
