    摘要: A device for producing an optical guide signal is disclosed. This device is particularly suitable for installation in airport runways and comprises a covered housing containing a light source and a prism wherein a portion of the prism projects above the cover of the housing such that light emitted from the source is both transmitted through the prism and is also internally reflected within the prism before emerging at one of the surfaces of the said projecting portion of the prism.
