A laser navigational system for a vehicle having a lighting assembly configured for emission of light. A lens array assembly receives incoming light from the lighting assembly and changes the direction of the incoming light received from the lighting assembly such that the outgoing light emanating from the lens array assembly is collimated in a first direction but diverges along a different, second direction. A scanning unit aligns with the lighting assembly to direct the collimated beam in two orthogonal directions. The lighting assembly, the lens array assembly and the scanning unit are configured to direct the light to form a visual beacon that guides navigation of the vehicle to a location.
