I'd like to adjust the headlights on my 2013 FX4. Anyone know how?

 

It's in the manual.

There is a little white "gear" that is visible if you look at the top of the headlight housing. Use a Phillips screw driver to catch the gears. If I remember correctly, right goes up, left goes down.

 

So I just did this a few months ago. If you look closely at your headlights, in the middle of the housing where the light shines through there is a small dot/bump. You should measure from the ground to this dot. Once you have this measurement find a good level piece of ground about 25 ft long. I used my driveway. Measure from the ground up on a vertical wall and make a mark at the same height as the dot on your light with painters tape. Place your truck facing the marks about 20-25 feet away from the wall. Turn your lights on( I used low beam ). The adjustments for your lights are right under the hood on top of the lights. You can use the a Phillips screw driver. You will then notice if your lights are high or low. In my case they were crazy high. Use the adjustment to move the lens so that the top of the beam is at the mark. Should be it.

 

Cool...I honestly hadnt read the entire manual yet. I wouldnt think they'd put that in there to keep folks from messing with it.
