A lighting device (10) for a route guidance system comprises a body (12) adapted to be mounted to a surface; at least one light source (18) housed within the body; a corresponding at least one outlet (14, 16) in the body from which light may be emitted; and focusing means (20) operable to focus the light into a beam projecting from the outlet. In one embodiment the device comprises a pair of outlets (14, 16) in the body, the focusing means being operable to focus light from the at least one light source into a pair of beams, one beam projecting from each outlet. In a second embodiment, the focusing means of the device is operable to focus the beam onto an adjacent surface. The device may be adapted to project static and/or moving images onto said adjacent surface. |
