Lighting and Horns: Description and Operation
OPERATIONThe Exterior Lamps are powered through the Main Light Switch or the Park Lamp Relay.
The Exterior Lamps light up when the Main Light Switch is moved to the "PARK" or "HEAD" position or when the Automatic Headlamp System is operating. The Main Light Switch is hot at all times, which allows the driver to leave the Exterior Lamps on whenever necessary.
On vehicles equipped with Anti-theft, the Anti-theft Controller Module flashes the Exterior Lamps when the System is triggered.
