Tool and Material Checklist:
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.

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.
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 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 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.
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.
