Search "jeep gladiator light bar" and the results lean toward overhead, windshield, and bumper bars built to light the road ahead. XKGLOW's XKdrive tailgate bar points the other way. It runs across the back of your Gladiator JT and signals to everyone behind you, with running, brake, sequential turn, reverse, and hazard lights, plus a Show Mode.
One thing to settle before you buy: as a Jeep Gladiator light bar, this is not a driving beam, and it will not light the trail. It is signal lighting for the back of the truck, with an app to tune it and a Show Mode for when the tailgate should be the attraction.
Two Kinds of Jeep Gladiator Light Bar
A forward bar is for you. It lights the road or the trail ahead. A tailgate bar is for everyone else, because it tells the driver behind you what your Gladiator is doing. Those are separate jobs, and XKGLOW builds a different bar for each.
If you want a beam, the XKmax Dual-Mode LED Light Bar pairs a driving beam with a color-chasing DRL strip. It comes in sizes from 7 to 50 inches and fits trucks, Jeeps, and UTVs. XKGLOW also lists bar brackets for the JL and JT in hood, cowl, A-pillar, and front bumper versions. Check each listing's bar size and series notes before you pair one with a bar. If you want the lights other drivers read, the XKdrive bar is the one to look at.
Five Functions and a Show Mode
On XKGLOW's store it is the XKdrive App-Controlled Truck Tailgate LED Light Bar. The Gladiator version is a 48-inch one-piece bar (SKU DR-TTL48J) that lists at $179.99, and it adds five functions across the tailgate:
- bright running lights
- brake lights
- sequential turn signals
- hazard lights
- a powerful white reverse light
The listing never describes replacing your factory tail lights. Turn Signal Learning detects your Gladiator's turn signal sequence and syncs the bar to it, so the animation tracks the truck's own signals. XKGLOW describes the integrated sequential turn signals as an OEM-inspired look that also improves visibility.
At a meet, Show Mode gives the tailgate chasing light effects and animated patterns. XKGLOW credits ultra-high-density LEDs for a smooth, continuous glow with no visible hotspots.
XKGLOW also lists a universal XKdrive bar in 48-inch and 60-inch sizes for full-size and mid-size trucks. On a Gladiator, order the Gladiator listing. If you drive a Wrangler instead, XKGLOW's spare tire brake light adds rear signaling and fits the JL, JK, and TJ.
What the XKdrive App Controls
The bar connects over Bluetooth to the XKdrive app, a free download on the App Store (listed there as XK-drive) that is also available on Google Play. The App Store lists iPhone support on iOS 14.0 or later, and its version history shows steady updates: version 1.0.9 added a new turn signal animation. Its description says the same app customizes XKdrive series headlights and taillights.
The XKdrive app is separate from the XKmax app that runs XKGLOW's accent kits, so a Gladiator carrying both lines uses two apps. In the XKdrive app you set:
- a startup animation
- a sequential turn signal animation
- a standard or F1-style strobing brake light pattern
- Show Mode effects and patterns
The controller has built-in memory, so patterns stay the way you set them.
Install and Towing
XKGLOW lists the install at under an hour. The bar mounts with the included automotive-grade VHB adhesive tape and mounting brackets. Built-in trailer detection compatibility and error-canceling technology are there to eliminate warning messages and additional modules, according to the listing. If you would rather hand it off, the listing links to XKGLOW's dealer locator for install help.
If you tow, add the 1-to-2 splitter wire for tailgate lights. It is a 4-pin Y-splitter that lets the bar and your trailer run together, so you never unplug the bar to hook up. The Gladiator listing offers it as a $21.59 add-on, which brings the XKdrive bar to $201.58 at listed prices.
The bar is IP67-rated waterproof, and the listing places it under XKGLOW's Limited Lifetime Warranty, which covers eligible products bought from XKGLOW or an authorized dealer. The warranty page lists LED failure, control module malfunctions, and wiring defects as covered under normal use. It excludes water intrusion caused by incorrect installation or sealing, so the install matters as much as the IP67 rating. Register the bar to activate your coverage.
XKdrive or the 3rd-Gen Bar?
XKGLOW's Jeep lineup lists a second 48-inch tailgate bar for the Gladiator, the 3rd-gen design. The table sets the two listings side by side.
| XKdrive bar | 3rd-gen bar | |
|---|---|---|
| Price | $179.99 | $155.99 |
| SKU | DR-TTL48J | XK041024 |
| Control | XKdrive app over Bluetooth | No app listed |
| Turn signal | Sequential, selectable animations | Integrated sequential |
| Brake light | Standard or F1-style strobe | Brake light |
| Show Mode | Yes | Not listed |
| Extra module | Not needed, per listing | Not needed, per listing |
| Waterproofing | IP67 | IP67 |
The XKdrive bar costs $24 more and adds the app: a custom startup animation, a choice of turn and brake patterns, and Show Mode. If you only need the five signal functions on the tailgate, the 3rd-gen bar lists all five. Both listings offer the same $21.59 splitter option for towing.
Pairing the Bar With the Rest of the Build
A tailgate bar handles the back of the truck. XKGLOW's fender vent lights fit the JL and Gladiator JT and run on the XKmax app. Their dedicated amber syncs to your turn signals and DRLs.
The main tradeoff in this build is the app split. XKdrive runs the tailgate and XKmax runs the accent kits, so you will open two apps. If one-screen control matters to you, know that before you order.

Frequently Asked Questions
What is the best LED light bar for a Jeep Gladiator?
It depends on which end of the truck needs the light. For the road ahead, pick a driving-beam bar such as XKGLOW's XKmax Dual-Mode LED Light Bar. For the tailgate, XKGLOW's XKdrive bar adds running, brake, sequential turn, reverse, and hazard lights, plus Show Mode.
Are tailgate light bars legal?
It depends on your state and on how you run the bar, so check your state's vehicle code first. Running, brake, turn, and reverse are functions your tail lights already perform. Keep Show Mode for meets and shows, and check local rules before you choose the strobing brake pattern.
Can you control a tailgate light bar wirelessly?
Yes. The XKdrive bar connects over Bluetooth to the XKdrive app, free on the App Store and also listed on Google Play. There you set the startup animation, turn animation, brake pattern, and Show Mode. It does not use the XKmax app, and the listing mentions no key fob.
Does a tailgate light bar have a reverse light and sequential turn signals?
The XKdrive bar does both. Its reverse light is white, and its sequential turn signals offer selectable animations. Turn Signal Learning syncs the bar to your Gladiator's own turn signal sequence, and the same bar carries running, brake, and hazard lights.
How hard is it to install a tailgate light bar on a Jeep Gladiator?
XKGLOW lists the XKdrive install at under an hour. The bar mounts with the included automotive-grade VHB adhesive tape and mounting brackets, and XKGLOW says built-in error-canceling technology eliminates warning messages. If you tow, add the $21.59 splitter so the bar and trailer run together.
