Lighting floor on sides of material handling vehicle to indicate limited or non-limited area

A method for controlling a light source device associated with a materials handling vehicle, wherein the materials handling vehicle comprises one or more sensing devices, the method comprising:

• sensing via the one or more sensing devices a first distance from a left side of the vehicle to a first boundary object and a second distance from a right side of the vehicle to a second boundary object;
• controlling the light source device to designate a first area to the left side of the vehicle as either a limited operation area or a non-limited operation area and to designate a second area to the right side of the vehicle as either a limited operation area or a non-limited operation area, the limited operation area corresponding to an area where the first or the second distance is less than a predetermined distance and the non-limited operation area corresponding to an area where the first or the second distance is greater than or equal to the predetermined distance;
• designating via the light source device, when one of the first or the second distance is less than the predetermined distance, the corresponding first or second area as a limited operation area in a first manner that can be observed by a person in the vicinity of the vehicle;
• and
• designating via the light source device, when concurrently the other of the first or the second distance is greater than or equal to the predetermined distance, the corresponding first or second area as a non-limited operation area in a second manner that can be observed by a person in the vicinity of the vehicle.
