Lights On Chime

When the headlamp switch is in the PARK or HEAD position, a ground signal is applied to the lights-on warning buzzer of the headlamp switch. When the LH front side door is opened, a ground signal is applied to the lights-on warning buzzer of the headlamp switch. If the headlamp switch is in the PARK or HEAD position and the LH front side door is opened, the lights-on warning will activate to remind the driver that the headlamp switch is in the PARK or HEAD position.
