For installing in cars and in different locations in which shocks are appearing the cover lighting covers having appropriate protections against detaching are being applied of lamps. Covers can also have arrangements zapłonowe, e.g. in discharge lamps, or different elements performing additional – functions crepuscular switches as equipping assembled outside covers, switches with motor detectors, arrangements reducing the power. Lighting covers let for directing a stream of light, they will disperse it or they are concentrating as well as they are changing its direction. Actually selected lighting covers apart from functional functions constitute the also interesting decorative element.
