Daytime Running Lamps (Domestic)

The Daytime Running Lamps (DRL) module is designed to automatically turn on the low beam headlamps through the headlamp switch output circuit and the front park/turn lamps through the park lamp feed circuit when the following is true:
^ The ignition switch is in the RUN position.
^ The headlamps are off.
^ The park brake is off.

The ambient light sensor is replaced by a jumper.
