FAQ

Is the T-Rex badge included?

No. The T-Rex badge is not included with any grille purchase. The badge is offered for sale separately.

Torch Grille Light Diagnostic

LED Light Diagnostics

All testing should be performed with a multimeter. A test light will not tell you voltage, it will only tell you if power is present or not.

Initial Diagnostics

Before you get into more in-depth testing ensure the following:

• 1. The heavy red wire is attached to the battery’s positive terminal.
• 2. The battery is fully charged and has a charge of 12 volts.
• 3. The heavy black wire is attached to the battery’s negative terminal.
• 4. Check fuse to ensure it is not blown.

Switch Diagnostics

• 1. The center wire should have 12 volts at all times.
• 2. One of the outside wires should have 12 volts when the switch is in the ON position.
• 3. The other outside wire goes to ground and runs through the harness and attaches to Terminal 85 on the relay.

Relay Diagnostics

• Terminal 30 – This is the main power wire that comes from the battery and should have 12 volts at all times.
• Terminal 85 – This terminal goes to ground through the heavy black wire attached to the battery’s negative terminal.
• Terminal 86 – This will have 12 volts when the switch is in the ON position. If no power here when the switch is on, then the switch is bad.
• Terminal 87 – This is the power out to the light that will have 12 volts when the switch is in the ON position. If Terminal 86 has 12 volts when the switch is on, but no voltage is read on this terminal, then the relay is bad.
• Terminal 87A – Not used.
• If the relay chatters when activated, then it is receiving low voltage (under 10.5 volts). Recheck voltage reading on Terminal 30 and 86 and make necessary corrections to restore 12 volts to these terminals.

What brand are T-Rex lights?

T-Rex LED lights are a private label ZROADZ brand that have been made to T-Rex specifications. T-Rex uses the highest quality CREE chips, an extruded aluminum housing and a polycarbonate lens with precision optics. The light pattern and distance is equivalent and sometimes better when compared to other leading brands of LED lights and light bars.

My T-Rex Torch grille has more than one light. Do I need a separate harness for each light?

T-Rex wiring harnesses are designed to accommodate a 15 amp draw. If the lights have a combined amp draw of less than 15 amps you can use the harness as is and simply wire the lights in series. If the combined amperage draw is above 15 amps, the fuse will need to be upgraded to the appropriate rating. T-Rex suggests using a fuse rated 5 amps higher than the anticipate amperage draw. The relay in T-Rex harness is rated at 30 amps and will accommodate any combination of light bars the company currently offers. The downside to using a single harness on multiple lights is that they are either all on or all off. Sometimes this is not desirable in which case separate harnesses are required.

Is my T-Rex product under warranty?

T-Rex grilles are covered by a limited lifetime structural warranty and a three-year warranty on the finish.

I need help getting my light to work on my T-Rex Torch grille

The T-Rex wiring harness is the best way to ensure your Torch grille operates properly. This harness simplifies wiring and ensures proper ground and power are applied to your Torch grille. In the event you choose to wire your Torch grille yourself T-Rex has found that the most common occurrence of non operation of their Torch LED lights can be linked to inadequate grounding or low voltage. All ground wires need to be affixed to a non painted metal surface or directly to the negative terminal on the battery. T-Rex Torch LED lights are reverse polarity protected and require a minimum of 10 volts to operate.

Does T-Rex build custom grilles?

At this time, T-Rex does not make custom grilles.

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 vehicle. 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 you would care for your vehicle’s factory chrome. Be sure to dry carefully with a soft micro fiber towel and never leave wet water spots as that may leave a blemish.

Matte Black Finish

Paint warranty applies to defects in material and/or workmanship and 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, Armor All®, 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 the matte paint. Remove foreign substances such as insect remains, tar, and road debris using a soft applicator and a mild solvent; saturate and soak the 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.

Gloss Black Finish

T-Rex grilles with a gloss black powder coat finish may be washed regularly as you would when caring for your vehicle’s 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 vehicle’s painted surfaces can be used to clean and maintain your T-Rex grille. A gloss powder coat finish can be cared for in the same fashion that you would care for your vehicle’s factory paint job. Never leave wet water spots as that may leave a blemish.
