How do I get rid of the inverted z pattern on the low beams? There is no instructions showing the new wiring or the adjustment. There is also an additional plug by the one adjustment. What is this for?
To address the low beam pattern, adjustment, and the extra connector on your TACTIK 9" Gen 2 LED Headlights:
1. The "Inverted Z" Beam Pattern
The "Z-pattern" (or stepped cutoff line) is actually a deliberate safety feature engineered into modern projector and LED headlights—it is not a defect.
Why it exists: The cutoff line drops lower on the left (driver's side) to prevent blinding oncoming traffic, and steps up higher on the right (passenger's side) to illuminate road signs, pedestrians, and the shoulder.
How to fix it if it looks "inverted" or uneven: If the pattern looks incorrect, it is almost always because the headlights need to be aimed or one side is sitting slightly rotated. Because these headlights mount into the factory JL/JT bucket locations, make sure the alignment tabs on the back of the housing are fully seated in their slots before tightening the mounting hardware. If they are slightly rotated, the beam pattern will tilt.
2. Aiming Adjustments
The factory JL/JT headlight buckets only feature a vertical (up/down) adjustment screw from the factory.
Where it is: You can adjust the height by using a T15 Torx driver on the adjustment screw located on the headlight assembly. Turning it clockwise or counterclockwise will raise or lower the beam.
How to aim: Park your Jeep on a level surface 25 feet away from a flat wall. Measure the height from the ground to the center of your headlight lens, and adjust your low beam cutoff on the wall so it sits roughly 2 inches lower than that measurement.
3. What is the Additional Plug next to the Adjustment Screw?
The extra, unused connector located near the adjustment screw on the back of the housing is for an optional motorized headlamp leveling system.
In certain international markets (such as Europe), vehicles are legally required to have manual or automatic cabin-controlled headlight leveling dials to adjust the beam angle when carrying heavy cargo or towing.
For US/North American Wranglers and Gladiators: Your Jeep does not have the cabin switch or wiring harness for this motorized system. You can simply leave this plug disconnected and capped. It will not affect the operation of your low beams, high beams, or DRL halo.

Hello, so i have the wiring installed for the turn signal and day time running lights. My jeep doesn't have day time running lights, but i thought if i turn my parking lights on then the halo would illuminate.
For the Tactik 9" Gen 2 LED Headlights, your logic is correct—you can wire the halo to illuminate with your parking lights, but it requires a specific wiring step.
The "Plug & Play" portion of the harness typically only covers the Low and High beams. To get the DRL Halo and Turn Signal functions working on a Jeep that didn't come with them, you need to tap into the vehicle's signal circuits.
How to wire for Parking Light activation
If you want the white halo to turn on whenever you rotate your light stalk to the Parking Light position, follow these steps:
Identify the Halo Wire: On the back of the Tactik headlight, there is a separate Red wire (usually designated for the DRL/Halo).
Locate the Parking Light Wire: On the Jeep JL/JT fender flare, find the wiring harness leading to the front marker/turn signal lamp.
The Wire to Tap: You are looking for the White wire with a Green stripe (this is the dedicated parking/marker light power).
Connect: Use a T-tap or solder the Red halo wire from the headlight to that White/Green wire.
Turn Signal (Optional): If you want the halo to flash Amber with your turn signals, connect the Yellow wire from the headlight to the White wire with a Tan stripe on the same fender harness.
Recommended Accessory
If you want to avoid splicing into your factory wires, Quadratec makes a specific DRL Adapter Wiring Harness (Part #97109-0925) for this exact scenario. It "tees" into your fender light plug and provides two pig-tail leads:
One lead triggers with the ignition (constant DRL).
One lead triggers with the parking lights (what you are looking for).
If all that is done correctly, the next step would be to reprogram or "flash" the Jeep's BCM. That can be done with Superchips SC-MOD Flashcal+ for 07-26 Jeep Wrangler JK, JL & Gladiator JT - Jeeps that did not have factory DRL's will need to do this.

Will this work right out the box with my stock halogen wiring (20 Gladiator Sport) or do I need to purchase something else to run the turn signals and DRLs?
Yes, and no. These are a direct fit and will plug-n-play. However, the PCU (Powertrain Control Module, think of it like the computer brain of your Jeep), needs to be re-programmed to tell it about the change from Halogen to LED. This can be done with a handheld programmer or at a local dealership that offers re-programming services (not all do). In the long run, customers typically find it more practical to purchase their own programmer as it offers MANY more applications than just light programming a single time: Superchips 3581-JT Flashcal+ for 20-25 Jeep Gladiator JT

Which LED headlights have the integrated defroster as described in your video on LED headlight differences.

Will I still need the wiring harness to integrate the turn signals after tazer programming?
Yes, the DRL harness is required for installation. Thanks for your inquiry.
Michael L.
If I’m swapping OEM leds to this will I still need the accessory wiring kit?
It is still required for the use of DRL Halo illumination regardless of your original lighting parameters. Sorry for the inconvenience.
Adam B.
My 2022 sport has halogens and no DRL. Other than buying the Quadratec DRL adapter wiring harness, is there any reprogramming that needs to take place to use the DRL on this light?
For JL & JT models that did not come factory-equipped with DRL, flash programming by a Jeep dealer will be required to recognize the DRL function of this headlight. Thanks for your inquiry.

2020 JL wrangler- Factory lights are Halogen. Will the TACTIK TT-LED-DRL-HALO-9 work as a plug and play replacement?
It is designed for plug and play use. Thanks for your inquiry.

Any warranty?
1 year limited warranty. Thanks for your inquiry.
