A fibre optic element is disclosed capable of a wide range of uses, including illumination, lighted fixed or variable signs, and decorative applications. The element is formed in one piece of transparent material and has one or more generally planar areas with integral extensions from one or opposite sides formed as a number of separable filaments such that the filaments can be bunched to form a flexible light conducting cable. Except for light escape zones via which light can escape from the planar area or areas, and the distal ends of the filaments, the element is covered by an internally reflective cladding layer such as to enable propagation of light through the filaments from the light source and in the plane of the planar areas, which rather than being strictly planar can be curved into various shapes. The light escape zones may be formed by replacing the cladding layer in those zones by a transparent layer of higher refractive index than the material of the element, or by using a diffusive or phosphorescent layer to divert or reradiate light out of the plane of the element.
