Please read the installation procedures thoroughly beforehand.

● In order for the lamp to perform at its full potential, use the relay harnesses manufactured by PIAA.
● All work procedures should be carried out in a location with adequate space. Place the shift lever in neutral or in the parking
position. Turn oﬀ the engine and set the parking brake.
● Make sure the engine compartment is adequately cool before starting work. Do not begin work if engine parts such as radiator,
oil-cooler or turbo parts are still hot.
● Do not add additional holes to the main body of the lamp. Also, do not apply adhesives or stickers to the lamp parts.
● Do not modify the lamp harness or the switch harness in any way. Such modiﬁcations may cause it to overheat or short. In somecases, it may cause the vehicle to catch ﬁre. PIAA will not be liable for damage caused by such modiﬁcations.
● When removing the battery terminals, do not touch the (-) and (+) terminals simultaneously. An electrical shock may occur.
Wear rubber gloves when carrying out such work procedures.
● Make sure the (-) and (+) terminals do not make contact with metal. It can be extremely dangerous if a short occurs.
● Make sure all bolts are tightly secure. If there are any loose bolts tighten them accordingly.
● After installing the lamp, adjust the lamp so the beam shines at least 40m in front of the vehicle. Also, adjust the lamp a little
toward the right so that it does not shine directly into the eyes of the opposing driver of a vehicle. (as traﬃc laws stipulate refer to p.6 for adjustment procedures)● After installing the lamp, make sure the headlamps, wipers and horn are working normally.
● When the battery terminal is removed, memory related to the clock, radio, audio system etc, will be aﬀected. After all work
procedures are completed, reset to the original settings. (For adjustment procedures refer to your car’s instruction manual)Caution Regarding Wiring / Please read thoroughly● When installing the wiring harness, strictly follow the cautionary points mentioned below. Incorrect or faulty wiring may cause
the lamp to operate improperly. In some cases, it may cause the vehicle to catch ﬁre.

● Before you begin always remove the (-) and (+) terminals.
Always remove the (-) terminal ﬁrst and make sure a short does not occur.
● When removing the battery terminals, always turn the key to OFF and remove it. Turn all other electrical units oﬀ such as
the light switch.
● When removing the battery terminals, if a cord (for an electrical unit) is connected, wind a length of vinyl tape around the(-) and (+) terminals to clearly identify them.
● Verify the (+) terminal (white) and earth (black) before connecting.
● Do not obtain (+) voltage from the alternator.
● Obtain the (+) current necessary for the switch from the (+) current used for the light switch.
(Do not use the same current used for a computer, radio or audio system)● Install the switch harness in a position where it will not make contact with high temperature surfaces such as the engine,radiator or engine compartment.
● Arrange the switch harness so that it does not make contact with moving parts.
● Do not place the switch harness on high-voltage wires such as brake or air-conditioning wires.
● If the switch harness makes contact with a part of the engine, apply a length of ordinary cushioned tape around the harness.
● When connecting the connector, insert until you hear an audible click● When removing the connector, hold the main body of the connector and pull it out. If excess force is used to pull the cord, it
may damage the connection, which could cause it to overheat.
● Make sure the harness does not sag. Use a harness band of vinyl tape to secure it in place to wiring inside the engine compartment.
● Before connecting it to the battery, verify the wiring arrangement.
● When connecting the battery terminal and or other electrical units, do not mistake the (-) and (+) terminals. Always start withthe (+) terminal.

DRIVING ／ Spot Light Aiming
Typically, driving lights are mounted above the front bumper about 14 cm -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.)
Measure driving lamp down angle
at the center of the beam hot spot.

Measure lamp height to center.

beams.

25 feet

FOG Light Aiming
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.)

【4】Troubleshooting……Verify each section according to the following.
1 After installation, if the lamp does not activate→ Check the wiring and make sure there are no faulty or irregular connections.
● If the switch illumination does not light up.
→ Verify the (+) wire from the switch is properly connected. If it is not correctly connected it will not activate.
→ Verify the fuse located on the vehicle’s wiring system. (the switch’s (+) wire should be connected to thefuse box). If it is burned out, connect it to another circuit.
→ If the switch itself is faulty, the same symptoms may exist. We recommend that the entire switch unit
be replaced.
→ Check the fuse for the switch harness. If it is burned out, follow instructions indicated in[ 3 Fuse replacement Procedures].
● The switch illumination lights up but when operating does not work.
→ Check the connecting (-) cord to the body earth.
→ There may be cases where each terminal related to speciﬁc sections may be incorrectly connected.
Check for any lose wires and also for dirt or grime.
→ Check the switch operation If an abnormality is found, replace it accordingly.

2 If the LED suddenly fails to light up …
→ Check the fuse located on the vehicle’s wiring system. If it is burned out, replace accordingly.
→ Check the fuse for the switch harness. If it is burned out, follow instructions indicated in[ 3 Fuse replacement Procedures].
→ There may be cases where each terminal related to speciﬁc sections may be incorrectly connected.
Check for any lose wires and also for dirt or grime.
→ Check the switch operation if an abnormality is found, replace it accordingly.

3 Fuse replacement procedures→ A short circuit may have occurred. Check the wiring system. If any type of damage isfound replace accordingly. (Non-replacement may pose a potential danger) (Short circuits are mainly
caused when wires are caught in the assembly or when there is a gap in the sleeve connected to the lamp harness).
