Abstract
A lighting system may include one or more light sources and one or more light guides. A lighting system may be integrated into a window, a skylight, an exterior light such as a headlight, a tail light, or a high center-mounted stop light, or other exterior or interior portions of a system such as a vehicle. The light guide may be embedded in an adhesive layer in a vehicle structure. The light guide may be index-matched to the adhesive layer so that unilluminated portions of the light guide are indistinguishable from the vehicle structure. The light guide may be formed from optical fibers. The optical fibers may include a light-scattering optical fiber that scatters light out of the vehicle structure. The light-scattering optical fiber may be fused to a non-scattering optical fiber that guides light from a light source to the light-scattering optical fiber.
