Dome Lighting; Courtesy Lights - Navistar ProStar+ Operation And Maintenance Manual

Dome Lighting

The overhead dome light is used for reading and for illumination
when entering and exiting the vehicle. The dome light on / off
is also controlled by pushing on the lamp lens. When either
entrance door is closed, the courtesy light will remain ON for
approximately 20 seconds or until the ignition switch is turned
ON. At that time, the lights will dim gradually until the light is off.
The Optional keyless entry key fob also turns on the light for a
time period when the Unlock button is pressed, and turns off the
light (dims gradually to off) when the Lock button is pressed.
