The present invention relates to LED lighting elements comprising translucent mouldings composed of polycarbonate-based moulding compounds, comprising a colourant mixture, carbon black, scattering additive and optionally white pigment, as used, for example, as covers with a day/night design. Through combination with one or more RGB-LEDs, it is possible to achieve surprising colour effects in night design with presence of a deep gloss effect in mouldings that are black and grey in day design.
