A device for directing a beam of light from a light source to a predetermined view range. The device is particularly suitable for installation inside the visor of a traffic signal, although other applications will be apparent. Two or more baffles are selectively positioned within a hollow housing. The baffles are uniformly formed and each has a plurality of apertures. The baffles are thin plates and are aligned so that each set of corresponding apertures creates a tunnel for a portion of a beam of light from the light source. Due to the thinness of the baffles, the 'tunnels' have no walls and no substantial surface area to deflect light rays outside the selected view range. This provides a sharp on-off effect at the periphery of the view range. Yet, a 'full ball' effect is provided within the view range. The exterior of the housing is contoured to fit inside the visor so that the position of the device, and therefore the direction of the light beam, may be adjusted by multi-directional rotation within the visor.
