BULB REMOVAL & INSTALLATION



  1. Fog lights have replaceable bulbs.
  2.  
  3. Reach behind the fog lamp housing and turn the bulb assembly 1 / 4 of a turn CCW, and then pull it out.
  4.  
  5. Pull the bulb out of the connector.
  6.  

To install:

  1. Clean the bulb glass surfaces.
  2.  
  3. Before installing the light bulb into the metal contacts, ensure that all electrical conducting surfaces are free of corrosion or dirt.
  4.  
  5. Push the new bulb into the connector.
  6.  


WARNING
Do NOT touch the glass bulb with your fingers. Oil from your fingers can severely shorten the life of the bulb. If necessary, wipe off any dirt or oil from the bulb with rubbing alcohol before completing installation.

  1. Insert the bulb assembly into the lens and turn CW to lock.
  2.  
  3. To ensure that the replacement bulb functions properly, activate the applicable switch to illuminate the bulb which was just replaced. If the replacement light bulb does not illuminate, either it is faulty or there is a problem in the bulb circuit or switch. Correct as necessary.

AIMING FACTORY FOG LIGHTS



Fog lights have a vertical adjustment screw (see photo). Fog light adjustment may be made using a wall, as described below

  1. Park the vehicle on a level surface, with the fuel tank full and with the vehicle empty of all extra cargo (unless normally carried). Be sure all tires are properly inflated. The vehicle should be facing a wall that is no less than 6 feet (1.8m) high and 12 feet (3.7m) wide. The front of the vehicle should be about 25 feet from the wall.
  2.  
  3. Measure the distance from the floor to the center of the fog lights and mark this on the wall with a horizontal line.
  4.  
  5. If aiming is to be performed outdoors, it is advisable to wait until dusk in order to properly see the beams on the wall. If done in a garage, darken the area around the wall as much as possible by closing shades or hanging cloth over the windows.
  6.  
  7. Turn the fog lights ON . Note the position of the pattern.
  8.  
  9. A properly aimed fog light beam will put the high intensity area about 4 inches (102mm) below the horizontal line made on the wall.
  10.  
  11. Use the adjustment screw to move the pattern up or down as required.
  12.  
  13. Be sure that both fog lamps have the exact same adjustment.
  14.  

FOG LAMP MODULE REMOVAL & INSTALLATION



  1. The module is secured to the bumper or fascia by two bolts or screws.
  2.  
  3. Remove the bulb.
  4.  
  5. Remove the mounting hardware and take off the lamp module assembly.
  6.  
  7. Installation is the reverse of removal.
  8.

INSTALLING AFTERMARKET AUXILIARY LIGHTS




NOTE
Before installing any aftermarket light, make sure it is legal for road use. Most acceptable lights will have a DOT approval number. Also check your local and regional inspection regulations. In certain areas, aftermarket lights must be installed in a particular manner or they may not be legal for inspection.

  1. Disconnect the negative battery cable.
  2.  
  3. Unpack the contents of the light kit purchased. Place the contents in an open space where you can easily retrieve a piece if needed.
  4.  
  5. Choose a location for the lights. If you are installing fog lights, below the bumper and apart from each other is desirable. Most fog lights are mounted below or very close to the headlights. If you are installing driving lights, above the bumper and close together is desirable. Most driving lights are mounted between the headlights.
  6.  
  7. Drill the needed hole(s) to mount the light. Install the light, and secure using the supplied retainer nut and washer. Tighten the light mounting hardware, but not the light adjustment nut or bolt.
  8.  
  9. Install the relay that came with the light kit in the engine compartment, in a rigid area, such as a fender. Always install the relay with the terminals facing down. This will prevent water from entering the relay assembly.
  10.  
  11. Using the wire supplied, locate the ground terminal on the relay, and connect a length of wire from this terminal to a good ground source. You can drill a hole and screw this wire to an inside piece of metal; just scrape the paint away from the hole to ensure a good connection.
  12.  
  13. Locate the light terminal on the relay; and attach a length of wire between this terminal and the fog/driving lamps.
  14.  
  15. Locate the ignition terminal on the relay, and connect a length of wire between this terminal and the light switch.
  16.  
  17. Find a suitable mounting location for the light switch and install. Some examples of mounting areas are a location close to the main light switch, auxiliary light position in the dash panel, if equipped, or in the center of the dash panel.
  18.  
  19. Depending on local and regional regulations, the other end of the switch can be connected to a constant power source such as the battery, an ignition opening in the fuse panel, or a parking or headlight wire.
  20.  
  21. Locate the power terminal on the relay, and connect a wire with an in-line fuse of at least 10 amperes between the terminal and the battery.
  22.  
  23. With all the wires connected and tied up neatly, connect the negative battery cable.
  24.  
  25. Turn the lights ON and adjust the light pattern, if necessary.
  26.  

AIMING



  1. Park the vehicle on level ground, so it is perpendicular to and, facing a flat wall about 25 ft. (7.6m) away.
  2.  
  3. Remove any stone shields, if equipped, and switch ON the lights.
  4.  
  5. Loosen the mounting hardware of the lights so you can aim them as follows:
    1. The horizontal distance between the light beams on the wall should be the same as between the lights themselves.
    2.  
    3. The vertical height of the light beams above the ground should be 4 in. (10cm) less than the distance between the ground and the center of the lamp lenses for fog lights. For driving lights, the vertical height should be even with the distance between the ground and the center of the lamp.
    4.  

  6.  
  7. Tighten the mounting hardware.
  8.  
  9. Test to make sure the lights work correctly, and the light pattern is even.
  10.
