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

## Abstract

A method is provided for controlling a light source device (200) associated with a materials handling vehicle (10), wherein the materials handling vehicle includes one or more sensing devices (40), comprising: sensing via the one or more sensing devices a first distance (D2) from a left side of the vehicle to a first boundary object and a second distance (Dl) 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.
