How to Install PIAA 2100 Series Xtreme White Halogen Lights - Fog Beam - Pair on your Silverado

• The work site must be clean and level with enough working space to complete
the job without distractions.

• When mounting the lamps mount them in such a place that they are free of
obstructions. Do not mount the lamps in such a place that they will obstruct an
existing automotive function. Do not mount them in such a manner that they
have a chance of contacting the road or curbs.

• The PIAA 2100X may be mounted upright or hanging down. It is very important
to make sure the "PIAA" that is molded into the lens reads right side up. If it will
not read right side up in its mounting location then the bracket will have to be
removed and repositioned so that it will mount right side up.

• When a mounting location is decided upon mount the lamp with the supplied
mounting screws, adhesive pads or other fasteners that will provide a secure
fitting to the vehicle.

• When lamp is mounted make sure to leave 1/8" clearance around the lamp for
proper heat dissipation and to protect painted surfaces from heat damage.

1. Before connecting any wires, the negative (-) battery terminal should be disconnected.

When connecting the wires on the harness, follow the wiring diagram and connect
them as in the diagram.

2. For proper lamp operation it is recommended that you connect the positive ( )
and negative (-) power supply wires directly to the corresponding battery terminals.
Do not take power directly from the alternator.

3. Find a power source to connect the switch power wire to. For legal operation of
driving lights, the power source must be one that is only powered when the high
beam of the headlamps is on. For legal operation of fog lights, the power source
must be one that is only powered when low beam of headlamps is on. To make
this connection use the supplied connector or any connector that is suitable
for this application.

Do not connect lights to turn signals or to lights that flash with an automotive alarm.

4. When running the wires through the engine compartment be sure to keep them
securely away from moving parts such as the fan and the throttle cable and away
from hot parts such as the exhaust manifold.

5. When the wiring is complete, test the system for operation. Do this by turning on
the system. If the system works, securely fasten the relay boxes and fuse holders
or tie them out of the way with wire ties. If the system does not come on, please
contact your PIAA dealer for assistance.

Typically, driving lights are mounted above the front bumper about 14-30 inches from the ground to provide extra high beam illumination. Driving lights can be mounted below the bumper, although they will not be as effective because the light will hit the ground sooner and reduce the range of the light.

Visual aim is made with the center of the beam hot spot 1.5 inches below the
lamp center at 25 feet with the lamp facing straight forward. (see below.)

Do not use driving lights into oncoming traffic.
Driving lights should never be the only foreword light source.
Driving lights should only be used with the headlamp high beams.

There are two important issues to address when installing fog lights, the first is to minimize the amount of return glare into the drivers eyes, and the other is to minimize glare into oncoming eyes. Both of those issues must be accomplished while putting as much light as possible on the road.

These fog/foul weather light aiming instructions are suggestions taken from common practice and the S.A.E. standard J583. Some modifications to these instructions may be necessary to minimize glare.

Visual aim is made with the top of the beam 4 inches below the lamp center at
25 feet with the lamp facing straight forward. (See below.)

Only use fog lights if they are aimed properly.
Fog lights should never be the only foreword light source.
Fog lights should be used with headlamp low beams.

The PIAA 2100X lamps have replaceable H3 style bulbs.
Use only 12V-H3-55 Watt bulbs.
Remove the two screws that are inset in the back of the lamp housing.
