AUXILIARY LIGHTS
Tool and Material Checklist:
- Auxiliary lights
- Electrical crimping pliers
- Wiring kit or regular pliers
- Drill
- Ratchet wrench and
- Drill bit, socket.
- Phillips screwdriver
- Safety glasses or goggles
- Masking tape
White your cars headlights are adequate in
normal driving circumstances, auxiliary lights
might be needed for special conditions such as fog
or extended night driving in rural areas. To make
the installation of auxiliary lights simpler, it is a
good idea to purchase a wiring kit with the lights.
A typical kit may include:
• Switch and switch panel
• 21 feet of 14-gauge wire
• Scotch lock connectors
• Solderless insulated terminals
• Sheet metal screws
• Nylon wiring ties
• Fuse and fuse carrier
• Fuse box tap clip
Before beginning, remember that regulations involving auxiliary lights differ from state to state.
For this reason, it is crucial that you familiarize
yourself with your state's regulations and adhere
to them.
MOUNTING THE LIGHTS
The mounting of auxiliary lights varies according to the type of lights being
installed For example, the ideal position for fog lights differs from
that of driving and passing lights.
Driving and Passing Lights
The positioning of these two types of lights is
extremely critical. If they are mounted too high,
they will blind your vision rather than improve it.
Instead of illuminating the road so that you can
see more clearly, the beams of light will be an obstacle that you have to look through to see the
road. If mounted too low, the beams will skim
across the rocks on the roadway instead of illuminating what you are trying to see. Driving and
passing lights should be mounted either directly
under the bumper or on top of it; refer to the appropriate chart for the proper mounting heights.
Keep in mind that most vehicles have built-in spots
for these lights.
NOTE: Try to place the lights as
far back as possible toward the grille to keep the
front profile of the lens behind the bumper. This
provides added protection from impact breakage.

Light Mounting Height Regulations (inches)
Fog Lights
Since fog rarely settles directly on the roadway,
this type of light will perform most effectively when
mounted low and aimed underneath the fog. Fog
lights are designed to cast a low, wide beam pattern that illuminates the road under the fog.
Always mount fog lights as low as possible. Refer to
the appropriate chart for specific mounting
heights.
Bumper Mounting
Be sure you know the correct mounting height
before beginning. The following instructions are
intended only as a general guide; be sure to follow
the manufacturer's installation instructions
carefully.
1. Make sure the lights are spaced an equal distancetromthaendwoflhi5iimperT
2. Drill the mounting holes.
3. Remove the hex nut and washer from the light.
4. Slip the mounting bolt through the hole in the
bumper.
5. Reinstall the washer and hex nut.
Do not tighten the light completely-leave it a little loose at this point for aiming purposes.
NOTE: If you have mounted rectangular lights
so that they hang down from the bumper, the bezels are upside down. Using a Phillips screwdriver,
carefully remove the two screws on each side of
the light. Now remove the bezel, lens, and reflector
as one assembly and reinstall it so that the writing
on the lens is right side up.
WIRING THE LIGHTS
The first step in wiring is to ground the lights. If
you are mounting two-wire lights, select a ground
point as close as possible to the lights; use either
an existing screw on the vehicle or a sheet metal
screw. The black wire on the auxiliary lights is usually the ground wire. Both lights can be grounded
with one wire.
Single-wire lights are grounded through the
mounting bolt and, in most cases, need no additional ground. lithe selected mounting surface
does not offer a ground for the lights, a ring terminal and 16-gauge ground wire can be attached to
each light using the adjustment screw. Attach
these wires to a suitable ground point.

The rest of the wiring procedure is illustrated in
the two schematics. The first shows a simple auxiliary lighting system; the second includes a relay
designed to handle the higher powered lights of a
more sophisticated system. In the latter, closing
the dashboard switch energizes the electromagnetic coil in the relay. This pulls the relay switch
closed and provides a path for the electric current
to follow and activate the lights. The general wiring procedure is as follows:
1. Using scotch lock connectors and 14-gauge
wire, connect the hot leads from both lights.
2. Run a wire from the lights toward the fire wall
for entry into the drivers compartment.
3. Use a piece of a coat hanger to pull the wire
through the fire wall. Try to route the wire next to
the factory wiring.
4. Once the wire is inside the driver's compartment, use nylon ties to bundle the wires in the
engine compartment.
5. Select a location for the switch panel.
6. Drill holes for sheet metal screws to secure
the switch panel. As an alternative, the switch can
be mounted directly into the dash instead, If you
choose to do this, use the hole in the switch panel
as a template for cutting the hole. Cut it small at
first, then enlarge it as necessary for a snug fit.
NOTE: Be sure to wear safety glasses or goggles
when using a drill or any other power tool.
7. Extend the wire from the lights to the switch
terminal marked LIGHTS.
8. Turn the switch to the OFF position.
9. Attach a slip-on terminal to the end of the
wire and connect it to the power terminal on your
switch.
10. Route the power wire coming from the
switch to either an auxiliary position in the fuse
block or another power source.
11. Cut the wire to the desired length and crimp
on a slip-on terminal to the end. Do not connect
the wire to the power source at this time.
12. Cut the power wire near the source.
13. Insert each end of the cut power wire into
each side of the in-line blade type fuse carrier.
14. Close each side and squeeze it with pliers
until it locks.
15. Insert the blade fuse.
16. With the switch still in the OFF position,
connect the power wire to a vacant terminal on the
fuse block.
AIMING THE LIGHTS
Proper aiming of the auxiliary lights is extremely
important. The driving lights are intended to supplement the high beam headlights, so they should
be aimed to give attention to the distance and
width of the beams. The passing lights are intended to supplement the low beam headlights and should be aimed in a similar plane with the
low beams. As mentioned earlier, fog lights should
always be aimed low for best results.
The correct aiming of auxiliary lights is accomplished by positioning them in relation to your
properly aimed headlights. Consult your owner's
manual and keep the following guidelines in mind:
1. Park the vehicle on level ground, approximately 25 feet from and perpendicular to a flat
surface such as a garage door.
2. If you are installing fog lights or passing
lights, turn on the low beams. Use masking tape to
mark the center of both headlights on the surface
they are shining on. Also mark the brightest horizontal portion of the beams.
3. If you are installing driving lights, turn on the
high beams. Again, use masking tape to mark the
center of both headlights on the surface they are
shining on, as well as the brightest horizontal portion of the beams.
These marks will help make the aiming process
easy. For specific instructions, refer to the appropriate section below.
Driving Lights
Driving lights are used to supplement the high
beams for greater distance and width; they should
be used only in conjunction with the high beams.
Aim the centers of the beams at the same level as
your high beam tape marks on the wall. Keep in
mind that the height requirements vary from state
to state, as seen in the chart. In some states it is
required that auxiliary lights respond automatically
to the fluctuations of the high and low beams. In
such cases, alterations to the wiring will be
necessary.
As for the horizontal setting of the lights, this is
a matter of personal preference. You might prefer
lighting the sides of the road at a distance rather
than concentrating the majority of light down the
middle of the road.
Passing Lights
Passing lights are used to supplement the low
beams to provide a more complete and uniform
pattern. Aim the centers of the beams at the same
level as your low-beam tape marks, or even slightly
lower. Again, keep in mind that height requirements vary from state to state. Consult the
enclosed chart and your local regulations.
The horizontal setting of the lights is a matter of
personal preference. A slight overlap of the beams
in the center will give evenly distributed light all
the way across the road, as well as very good
width. A greater overlap of the beams, on the other
hand, will increase the center light and reduce the
overall width of the lights.
Fog Lights
The vertical aiming of fog lights is critical; they
should be aimed parallel to the ground or slightly
lower. If fog lights are adjusted for distance by
aiming them in even a slightly higher angle, their
effectiveness will be greatly reduced. Fog lights
aimed in this manner also tend to offend other motorists. Again, your personal preference dictates
the horizontal setting of the lights.
After initial use, some minor adjustments of your
lights might be needed. For instance, you might
prefer more center light or a wider beam, or it
might be necessary to raise or lower the beams.
And remember, if oncoming motorists are regularly flashing their high beams at you while you are
using your auxiliary lights, this is a sure sign that
you should lower the beams.
