This group includes incandescent lamps which may be dimmed. The following lamps are part of this group:

The PNL circuit breaker in the I/P Fuse Block supplies battery voltage to the headlamp switch. When the headlamp switch is placed in the PARK or headlamp ON position, current flows from the headlamp switch to the I/P dimmer switch. The I/P dimmer switch has a variable resistor inside of it that the current will flow through. The setting of the variable resistor will determine the amount of voltage drop across it. After the current flows through the I/P lamps dimmer switch, it flows to S233. Splice 233 distributes the voltage to all of the lamps listed above. All of the lamps listed above ground at G101or G102.

Driver controls include the following components:

The daytime running lamps (DRL) control module is the only module in the lighting system of this vehicle.
