All or some of the optical fibers comprise at least one coupling section. Each coupling section is disposable or disposed in a socket of the lighting device to receive light from a light source of the lighting device. The optical fibers include at least one light decoupling section being part of at least one illumination section of the woven flat body. The woven flat body and/or the at least one light decoupling section of the optical fibers include at least one reflecting element to decouple light from the optical fibers. ## Claims ### Claim 1 A light guide for a lighting device for a vehicle, comprising: at least one woven flat body and a plurality of optical fibers, which at least partly build the flat body; wherein all or some of the optical fibers comprise at least one coupling section, each coupling section is disposable or disposed in a socket of the lighting device to receive light from a light source of the lighting device, the optical fibers comprise at least one light decoupling section being part of at least one illumination section of the woven flat body, the at least one light decoupling section of the optical fibers comprises at least one reflecting element to decouple light from the optical fibers, and the reflecting element is used in the light decoupling section of the optical fibers, wherein the woven flat body comprises at least one reflecting element to decouple light from the optical fibers, the at least one reflecting element comprises reflecting threads, shreds, and particles, and has a metallic surface. ### Claim 2 (depends on 1) The light guide of claim 1, wherein the woven flat body comprises at least one of non-optical fibers, fiberglass, Kevlar, carbon and cotton. ### Claim 3 (depends on 1) The light guide of claim 1, further comprising a protection layer covering at least one outer surface of the woven flat body. ### Claim 4 (depends on 1) The light guide of claim 1, wherein the protection layer comprises a translucent coating, and the light guide comprises an additional translucent, opaque and/or colored, coating. ### Claim 5 (depends on 1) The light guide of claim 1, wherein some or all of the optical fibers comprise a reflecting end portion. ### Claim 6 (depends on 1) The light guide of claim 1, further comprising: first optical fibers disposed in or at a first socket and comprising a first light decoupling section that is part of a first illumination section of the woven flat body; second optical fibers disposed in or at a second socket and comprising a second light decoupling section that is part of a second illumination section of the woven flat body; and further optical fibers disposed in or at a further socket and comprising a further light decoupling section that is part of a further illumination section of the woven flat body. ### Claim 7 (depends on 1) The light guide of claim 1, wherein the woven flat body is flexible or stiff and the woven body is solvable; and attachable on a vehicle part or is integrated as insolvable body, in particular builds an outer cover for the vehicle part. ### Claim 8 (depends on 1) The light guide of claim 1, wherein the woven flat body is constructed as a tight sinusoidal wave for creating an effect of multiple light sources, and the light output is consistent along the illuminated length. ### Claim 9 (depends on 1) The light guide of claim 1, wherein the woven flat body is constructed as a flexible tube enabling the illumination section to be guided into position. ### Claim 10 (depends on 1) The light guide of claim 1, wherein the woven flat body enables curved sections to be created with a radius of curvature of 5 mm or less. ### Claim 11 (depends on 1) A lighting device for a vehicle comprising: at least one light source comprising a light emitting diode (LED); at least one socket for receiving light from the light source; at least one light guide comprising the light guide of claim 1, wherein all or some of the optical fibers comprise at least one coupling section, each coupling section is disposable or disposed in or at the at least one socket to receive light from the light source; wherein the optical fibers comprise at least one light decoupling section that is part of at least one illumination section of the woven flat body; and wherein at least one of the woven flat body and the at least one light decoupling section of the optical fibers comprises at least one reflecting element to decouple light from the optical fibers. ### Claim 12 (depends on 1) The light guide of claim 1 wherein the light guide is part of a vehicle part comprising at least one of a rear view mirror, an external camera, a camera pod, a turning signal, an interior light, frontlight, and a backlight. ### Claim 13 (depends on 6) The light guide of claim 6, wherein the first illumination section and the second illumination section are adapted to create colored streams of color; or segments of different color, and the first illumination section and the second illumination section are adapted to be turned off and on independently. ### Claim 14 (depends on 11) The lighting device of claim 11, wherein at least one of a lens, a prism, a filter and reflector is disposed between the light source and the at least one socket is configured to interact with the light emitted by the light source. ### Claim 15 (depends on 11) The lighting device of claim 11, further comprising: at least one control unit configured to regulate at least one of intensity and color of the respective light emitted by the at least one light source. ### Claim 16 (depends on 11) The lighting device of claim 11, wherein the at least one light source comprises at least one RGB tri-color light emitting diode (LED) for variable output color. ### Claim 17 (depends on 11) The lighting device of claim 11, further comprising: a plurality of light sources; optic elements; sockets; bundles of optical fibers, first optical fibers disposed in or at a first socket and comprising a first light decoupling section that is part of a first illumination section of the woven flat body;
