Adjust headlights?
The instructions in your Owner's Manual are pretty decent, but I'll add a couple of things that I found. First, you'll need a 4mm box ratchet type wrench to make your life easier. Most professional tool vendors carry a special wrench just for this job. I have the Snap-On / Blue Point version and it works great.
Second, when the manual says turn the screw counter clock wise (CCW), they mean "as you're standing at the front of the truck looking at the front of the headlight." (The adjuster is on the back side.) This is the opposite of what I'm used to which would be "facing the fastener."
Third, when you turn the screw, you're actually only moving the reflector surrounding the bulb, not the entire housing, so don't expect to see the housing move.
Finally, when you start your adjustment, I'd recommend counting the "turns of the screw" or "swings of the wrench" and direction. You'll want to see if you're going n the right direction first, then you'll want to move both headlights the same amount / number of turns. Good luck!

OK boys and girls, here's another helpful hint. When you think you have your headlight aim where you want it, I have one last check that I perform.
Park the truck on level ground where you have 50-75 feet of open space in front of it. Turn your headlights on (low beam) and walk out about 50 feet in front of the truck. Turn around and face the truck and position yourself facing right down the middle of the hood. Now, slowly squat down and watch the headlights. Does one get brighter sooner than the other? If so, that headlight is aimed higher. (You're seeing the "cutoff" in the beam pattern.) Fixing the problem is a simple matter of some more wrench work.
This will avoid what you sometimes see with oncoming cars that really pisses you off where one headlight is aimed higher than the other. (It can also be lateral aim, but not on the new F-150's.)

The exact proceedure for adjusting the headlights is as following per the 2004 F150 Service Manual CD.
1. Position the vehicle 28 feet from the face of the headlights to a verticle surface on perfectly flat ground.
2. mark a line or tape a line exactly 8 feet high from the floor.
3. With the high beams on adjust headlights until the very top edge of the beams are aligned and touching the bottom edge of the line.
4. It best to do this proceedure in total darkness.
Note: As previously mentioned, there is no side to side adjustments.
I lowered the rear of my '04 STX 2 inches. This proceedure wotks great.

HATE to dig this old topic up!!!!
I tried to adjust my head lights with the above steps and it was wasy to high!
NOT sure if that only works for 04-05 trucks I have a 01
Just thought I would drop a not.
I did the 50 feet in front of truck step and that makes it easy to tell if lights are even after to make the even against the wall.

01f150supercrew,
I would not use a set of instructions to adjust the headlights for a 2004 on your 2001 F150.
You really need the instructions for your truck. I can't imagine what the difference would be but if you have adjusted the headlights and there is still something not right, I would supect that either you're doing something wrong or there is something different about how the headlights adjust on your '01 truck.

your owners manual has the right instructions. your headlights should be fairly level or slightly down. when I set my headlights I measured up to the center of the element on the bulb. I parked about 30 feet away from a wall on level ground and adjusted the bulb till the top or the light beam was at the same level. this points them just slightly down but not too much. this was a slight variation from the owners manual but it worked well. I have had no problems with it being pointed too high.



..... well it doesnt really bother me!
