There are a couple of different times when you'd turn off your headlights. You'd turn off your headlights when the car is off for example.
Park on a level surface and measure and mark 25ft. forward of the truck. Wait for condition of low light. Start the truck's engine and turn the headlights on, set to LO beam. Adjust the headlights so that the brightest part of each beam hits the ground 25 ft directly ahead of the lens (not to the left or right.) You may need a #2 Phillips head screwdriver to turn the adjusters.
In the tunnel, you go over the trucks. Enroute you find some keys that open the car on back of the wrecker truck. Enter and turn on the lights. (Clicking the control will tilt the truck so that the headlights shine on the zombies.)
