How to Install PIAA 410 Series 3.5 in. Square White Halogen Lights - Driving Beam - Pair on Silerado

When connecting the wires on the harness, follow the wiring diagram and the sequence below,

> Before connecting any wires disconnect the negative () battery terminal.

Note: When running the wires through the engine compartment 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.

> 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 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.

> Run switch wires into driver's compartment. If wires pass through the fire wall a rubber grommet must be used., Connect switch to switch wires and mount switch in desired location.

> Connect relay ground to chassey or battery negative (-).

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

> Carefully connect harness to bulbs.

> 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.,

> Aim lamps according to Light Aiming instructions on page 5.

> Tighten all fasteners.,

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.
