Abstract
An exit lighting system for a work vehicle includes an exit light, controller connected to the exit light, and an operator interface connected to the controller for selecting various modes of operation. The operator interface includes a display that shows several exit lighting settings and an operator input device that permits the operator to adjust the settings, such as by turning the exit lighting on and off, selecting the exit light duration, and checking a light sensor to be sure it is dark before using the exit lights. The exit lights turn on when one or more of several operator selectable conditions exist: the operator doors are opened or closed, the atmospheric lighting is low, the headlights are on (prior to ignition off), and the ignition switch is turned off.
