WARNING
PLEASE CONSULT YOUR LOCAL AUTOMOTIVE ELECTRICAL PROFESSIONAL FOR INSTALLATION SERVICES AND ADVICE. T-REX IS ONLY EQUIPPED
TO PROVIDE BASIC TECHNICAL ASSISTANCE DUE TO THE DIVERSITY OF VEHICLES, VEHICLE OPTIONS & MODIFICATIONS AND LIGHTING
CONFIGURATION OPTIONS AVAILABLE. T-REX Truck Products cannot be held liable due to improper component installation and / or faulty wiring.
GENERAL GUIDELINES
LED Lights & LED Light Bars operate at relatively high currents and should only be installed by qualified personnel with experience in
switched / relayed high draw DC Circuits.
- Light Bars are designed for use only with standard 12v DC power systems
- Light Bars are for OFF-ROAD USE ONLY. Check your local laws & regulations regarding vehicle mounted lights.
- Some Light Bars are equipped with waterproof connectors while others are simply pig-tailed
- Red Wires = POSITIVE | Black Wires = NEGATIVE
- ALWAYS install your lights on a fused circuit. Basic fusing guidelines: maximum 5A for every 10” of LED Light Bar.
GENERAL USE, INSTALL AND ADJUSTMENT TIPS
NOTE 1: T-REX Torch Series Grilles (with LED Light Bars installed), and LED Light Bars themselves are for OFF-ROAD USE ONLY.
NOTE 2: Light Bars in Torch Series Grilles are installed flush with the grille from the factory. This may or may not be the ideal angle for each light
depending on the configuration of your vehicle and its options and/or modifications. To adjust the angle of your light bars simply loosen the
mounting hardware on either side of each Light Bar, rotate the Light Bar to adjust the angle, then tighten the hardware once the desired angle is
achieved (please be careful not to over-tighten the mounting hardware or scratch the protective powder-coat finish). It is best to adjust the angle
with the vehicle on level ground with the lights facing a wall, garage door or other solid barrier at a distance of approximately 25-30 feet.
NOTE 3: Please consult a qualified automotive electrical professional for light bar wiring installation.
NOTE 4: An optional universal wiring harness (part# 639HAR1) is also available that includes high-heat & oil/fuel resistant wires, waterproof
connector, 12v relay, 12v rocker switch, inline fuse holder. Our universal wiring harness significantly expedites the installation process but is not a
vehicles specific “Plug & Play“ product and does not eliminate the need for a professional installation.

GRILLE CARE INFORMATION
T-REX grilles are finest in the industry but do require normal care. Wash regularly as you would when caring for your vehicles. Never use dish soap.
POLISHED FINISH
T-REX polished grilles should be waxed at the same time that you wax the vehicle and can be cleaned with soap and water. A polished finish can
be cared for in the same fashion that would care for your vehicles factory chrome. Never leave wet water spots as that may leave a blemish.
GLOSS BLACK FINISH
T-REX Grilles with Gloss Black Powder Coated Finish may be washed regularly as you would when caring for your vehicles finish using soap
and water. T-REX grilles should be waxed at the same time that you wax the vehicle. As a general rule, anything you use to clean your vehicles
painted surfaces can be used to clean and maintain your T-REX grille. A Gloss powder Coated Finish can be cared for in the same fashion that
you would care for your vehicles factory paint job. Never leave wet water spots as that may leave a blemish.
MATTE BLACK FINISH
Paint warranty applies to defects in material and / or workmanship, it does not cover the matte finish surface appearance.
To enjoy the matte appearance for many years to come, please follow these owner care and maintenance tips.
Get a no-shine matte car wash soap that uses no fillers, no silicone, and won’t strip your matte paint of its layer of protection.
Do not use wax, detail spray, armorall®, or any products made for normal paint. Use only products specifically developed for matte
finish paint. Do not use products that are even mildly abrasive, such as polishes, glazes, or rubbing compounds. Do not use mechanical
cleaners or polishers. Do not use terrycloth, cloth, or paper towels. Do not rub the finish vigorously, this will burnish the paint finish,
causing a permanent shiny spot. Shiny spots cannot be removed.

Do not use commercial car wash facilities or their shine enhancement products. Most car wash brushes, large mechanized “towels,”
and shine enhancement products can damage matte paint.

Remove foreign substances such as insect remains, tar, and road debris using a soft applicator and a mild solvent; saturate and soak
area before cleaning—rub lightly.

Hand-wash with a soft wash mitt and mild cleaning product safe for matte paint. Use microfiber cleaning cloths with alcohol-based window
cleaner for basic surface clean-up.
