A miniaturized fiberoptic illuminating device, includes fiberoptic cables providing a plurality of optical fibers for conducting light and ferrules inserted over end portions of the cables. Apertures which are formed from the output ends of each optical fiber pass the light from the optical fibers. The device also includes a single optical lens, which may be a cylindrical lens or a modified cylindrical lens having different lens shapes formed into the surface thereof, aligned with the apertures for receiving light emitted from the optical fibers and passed through the apertures. The lens focuses the light in a desired pattern and may be rotated to clean the lens and/or adjust the beam pattern. The device also includes a housing having a row of spaced apart cavities receiving and supporting the ferrules and a single cavity spaced forwardly of and extending transversely to the row of cavities which contains the lens. The single cavity is spaced forwardly from forward ends of the row of cavities. The housing also has an elongated slot which intersects forward ends of row of cavities and a rear side of the single large cavity and is disposed between the row of cavities and the large cavity for providing a passage from the apertures to the lens to pass light emitted from the optical fibers through the apertures to the lens.
