How do you align or focus headlight beams that are to low or to high?
AIMING THE HEADLIGHTS
The
headlights must be properly aimed to provide the best, safest road
illumination. The lights should be checked for proper aim and adjusted
as necessary. Certain state and local authorities have requirements for
headlight aiming; these should be checked before adjustment is made.
CAUTION
About once a year, when the headlights are replaced or any time
front end work is performed on your vehicle, the headlight should be
accurately aimed by a reputable repair shop using the proper equipment.
Headlights not properly aimed can make it virtually impossible to see
and may blind other drivers on the road, possibly causing an accident.
Note that the following procedure is a temporary fix, until you can
take your vehicle to a repair shop for a proper adjustment.
Headlight adjustment may be temporarily made using a wall,
as described below, or on the rear of another vehicle. When adjusted,
the lights should not glare in oncoming car or truck windshields, nor
should they illuminate the passenger compartment of vehicles driving in
front of you. These adjustments are rough and should always be
fine-tuned by a repair shop which is equipped with headlight aiming
tools. Improper adjustments may be both dangerous and illegal.
For
most of the vehicles covered by this guide, horizontal and vertical
aiming of each sealed beam unit is provided by two adjusting screws
which move the retaining ring and adjusting plate against the tension
of a coil spring. There is no adjustment for focus; this is done during
headlight manufacturing.
Because the composite headlight assembly is bolted into position, no
adjustment should be necessary or possible. Some applications, however,
may be bolted to an adjuster plate or may be retained by adjusting
screws. If so, follow this procedure when adjusting the lights, BUT
always have the adjustment checked by a reputable shop.
Before removing the headlight bulb or disturbing the headlamp in
any way, note the current settings in order to ease headlight
adjustment upon reassembly. If the high or low beam setting of the old
lamp still works, this can be done using the wall of a garage or a
building:

Hope helped with this information. Good luck (remember rated this help).
Turn the engine off, open the hood, and disconnect the negative battery cable (--) with your pliers.
Locate the power distribution box against the firewall on the driver's side of the engine compartment. Flip up the latch and remove the plastic cover.
Determine which headlight fuse you want to replace. The 2001 Ford Focus uses four headlight fuses--one for each headlight. Fuse number 16 is for the passenger side low beam; fuse number 17 is for the driver's side low beam. Fuse number 26 is for the passenger side high beam; fuse number 27 is for the driver's side high beam.
Grasp the fuse with your fingers and pull it straight out of its mount. Insert the new fuse in its place. Replace the plastic cover and reconnect the negative battery cable.
