A tailgate light bar can give following drivers a wider signal when you brake, turn, or reverse. The Nilight TR-04 is a 60-inch, triple-row LED strip designed to add running, brake, reverse, turn-signal, and strobe lighting across the rear of a compatible vehicle. Its 504 LEDs, IP67-rated construction, and adhesive mounting make it a practical visibility upgrade. However, you must measure the mounting area and plan for a separate reverse-light wire before installation.
Quick Verdict
Rating: 8.4/10, Recommended with caveats
Best For: Owners of full-size trucks and other compatible 12V vehicles who want a wide, multifunction rear lighting add-on.
Bottom Line: The Nilight TR-04 combines six useful lighting functions with a high LED count and weather-resistant construction. Installation is relatively simple, but the reverse light needs an additional wire connection, and the fixed 60-inch length will not fit every vehicle.

What Is the Nilight TR-04 Truck Tailgate Bar?
The Nilight TR-04 is an exterior LED strip that mounts in the recessed area between a vehicle’s tailgate and rear bumper. It measures 60 inches long and uses 504 LEDs arranged across three rows to create a broad lighting signal.
The strip provides dark-red running lights, brighter red brake lights, white reverse lights, sequential amber turn signals, and a sequential strobe function. It is intended as an additional visibility accessory for compatible 12V trucks, pickups, SUVs, vans, RVs, and trailers.
The TR-04 is not a replacement for your vehicle’s original rear lights. It works best when you have enough straight mounting space, compatible trailer wiring, and safe access to the reverse-light circuit.
Key Takeaways
- The fixed 60-inch strip uses 504 LEDs arranged in three rows.
- Six functions cover running, braking, reversing, left turns, right turns, and sequential strobe lighting.
- The standard 4-pin connector simplifies the main lighting connection on compatible vehicles.
- The white reverse-light function requires a separate wire connection to a suitable 12V reverse-light source.
- The flexible silicone strip has an IP67 water-resistance rating.
- Adhesive backing and additional mounting hardware are included.
- You must check mounting space, wire routing, connector access, and local lighting rules before installation.
Before You Buy: Confirm that your vehicle has a straight 60-inch mounting area and a compatible 12V electrical system. The 4-pin plug alone does not power the white reverse light, which requires a separate reverse-wire connection.
Who Should Buy It?
Best For
- Owners of full-size trucks with enough straight space for a 60-inch strip.
- Drivers who want running, brake, reverse, turn-signal, and strobe functions in one accessory.
- Vehicles with compatible 12V trailer wiring and an accessible reverse-light circuit.
Skip If
- Your vehicle cannot accept a fixed 60-inch strip without bending, trimming, or blocking another component.
- You want an installation that uses only a 4-pin plug with no additional reverse-light wiring.
- You need decorative, app-controlled, or remote-controlled lighting.
Lighting Functions and Rear Visibility
The TR-04 combines several rear-lighting signals in one strip. The dark-red running light stays less intense than the bright-red brake function, helping drivers behind you distinguish normal nighttime illumination from braking.
The sequential amber turn signals spread across the strip in the direction of the turn. This gives following traffic a wider visual cue than a small factory lamp alone. The white LEDs activate for reversing once the separate reverse wire is connected correctly.
The strobe function adds another visible pattern, but you should not assume every lighting pattern is legal for unrestricted road use. Check local vehicle-lighting rules and keep all factory lights visible and working.
Triple-Row LED Layout
The strip contains 504 LEDs across its 60-inch length. The triple-row arrangement produces a wider illuminated area than a basic single-row strip, which can make braking and signaling easier to notice from directly behind the vehicle.
Brightness alone does not guarantee safe driving. Dirt, snow, poor placement, failed connections, or blocked factory lights can still reduce visibility. Inspect the strip regularly and continue using your mirrors, camera, and normal driving checks.
Build Quality and Weather Protection
Nilight uses a flexible silicone design rather than a rigid metal housing. This lets the strip follow a mildly shaped mounting area, but you should not force it around sharp bends or folds.
The product carries an IP67 rating. This supports protection against dust and temporary water exposure when the strip and wiring remain intact. It does not make damaged connectors, cut insulation, or poorly sealed splices waterproof.
The manufacturer lists a working lifespan of more than 30,000 hours. Treat that figure as a rated product specification rather than a guarantee. Heat, road salt, strong sunlight, pressure washing, wiring quality, and mounting conditions can affect actual service life.
Installation Process and Wiring Requirements
The adhesive-backed strip is designed to sit between the lower edge of the tailgate and the bumper shelf. Before removing the backing, hold the strip against the vehicle and check tailgate movement, camera visibility, parking sensors, license-plate clearance, and access to the trailer connector.
The standard flat 4-pin connector handles the main trailer-light connection on a compatible vehicle. However, the white reverse-light function needs the additional reverse wire connected to a suitable 12V positive reverse-light source. This step may require access to the vehicle’s wiring rather than a plug-only installation.
Test the left and right turn signals before attaching the strip. The wire bundle must face the correct side for the sequential signals to move in the intended direction. Nilight also includes additional mounting hardware that can support the adhesive installation.
Pro Tip: Connect and test every lighting function while the strip is still loose. Confirm the signal direction and reverse-light operation before exposing the adhesive or installing the extra mounts.
Setup Tips Before First Use
- Measure the full area: Confirm that the mounting path can accept a 60-inch strip without covering sensors, cameras, trim, or the license plate.
- Clean away wax and grease: Adhesive will not bond well over road film, silicone-based detailing products, or loose dirt.
- Let the surface dry: Trapped moisture can weaken the bond and encourage the ends to lift.
- Check wire direction: Test both turn signals before mounting so the sequential pattern moves correctly.
- Plan the reverse connection: Locate the correct 12V reverse-light source before securing the wire bundle.
- Protect the wiring: Route the cable away from exhaust heat, sharp metal, moving tailgate parts, and trailer-hitch contact.
- Use the included supports: Add the supplied mounting hardware where practical instead of relying only on adhesive.
- Test after installation: Check running, brake, reverse, left-turn, right-turn, and strobe functions before driving.
Compatibility and Safety
The listing describes the TR-04 as a universal-fit 12V accessory and names vehicles such as the Dodge Ram, Ford F-150 and F-250, Chevrolet Silverado, GMC Sierra, and Toyota Tundra. Universal fit does not mean guaranteed fit on every model year, trim, bumper, or aftermarket setup.
Measure your own vehicle and inspect its wiring before ordering. Tailgate-assist systems, rear cameras, parking sensors, step bumpers, trailer plugs, and aftermarket bumpers can reduce the available mounting area.
Keep your factory brake lights, reverse lights, and turn signals operational. Incorrect wiring can cause failed signals, blown fuses, or unwanted electrical behavior. Use the supplied instructions, and have an automotive technician complete the wiring if you cannot identify the correct circuit safely.
Rear-facing white, amber, and strobe lighting rules vary by location and intended use. Confirm your local requirements before using nonstandard patterns on public roads.
How It Performs in Real Use
For Daily Driving
The red running and brake functions create a wide signal across the rear of the vehicle. In stop-and-go traffic, this can make your braking action easier to notice, especially when the strip is mounted straight and kept clean.
For Turning and Lane Changes
The sequential amber LEDs provide a directional pattern for left and right turns. Correct mounting orientation matters because attaching the strip in the wrong direction can reverse how the pattern travels.
For Reversing at Night
The white LEDs add light behind the vehicle when the reverse wire is connected correctly. This may improve visibility near a driveway, trailer, campsite, or work area, but it should support rather than replace mirrors, a backup camera, and a physical check of the area.
For Towing and Outdoor Use
The 4-pin connector suits vehicles that already use trailer-style wiring. When towing, confirm that the bar does not occupy the connector needed by the trailer or interfere with hitch components. The IP67-rated strip can handle normal exterior exposure, but connectors and added wire splices still need protection.
Maintenance and Long-Term Durability
Adhesive-mounted exterior accessories need occasional inspection. Check both ends of the strip after automatic car washes, freezing weather, high summer temperatures, or long drives on rough roads.
Clean the lens surface gently so mud and road film do not reduce light output. Avoid aiming a pressure washer directly at the strip edges, connectors, or wire entry points.
Inspect the fuse, cable insulation, brackets, and reverse-wire connection if a function stops working. A wiring fault may affect one lighting mode even when the rest of the strip still operates.
Pros and Cons
Pros
- 504 LEDs provide broad illumination across a 60-inch triple-row strip.
- Six functions combine running, brake, reverse, turn-signal, and strobe lighting.
- Standard 4-pin connector simplifies the main connection on compatible vehicles.
- IP67-rated silicone construction suits exterior vehicle use.
- Package includes extra mounting hardware and a user manual.
Cons
- The fixed 60-inch length does not fit every truck, SUV, bumper, or tailgate design.
- The white reverse light requires a separate wire connection beyond the 4-pin plug.
- Adhesive performance depends on preparation, temperature, surface texture, and long-term exposure.
Is It Worth the Price?
The Nilight TR-04 offers strong value for the price when you want several rear-lighting functions in one exterior strip. The 504-LED layout, IP67 rating, extra mounting hardware, and two-year warranty make it more complete than a basic red-only tailgate strip.
You will get the most value when your vehicle already has compatible 12V trailer wiring and enough straight space for the full 60-inch length. The installation becomes less convenient when you must modify the mounting area, extend wiring, or pay for professional electrical work.
It is a smart buy for everyday visibility on a compatible vehicle. It is not the best fit when you need a shorter strip, a rigid housing, app controls, or an installation with no additional reverse-light connection.
How It Compares to Alternatives
Nilight also sells simpler 60-inch single-row tailgate strips with fewer LEDs. Those options may suit you when you want basic running, brake, turn, and reverse functions without the wider triple-row layout.
A shorter 30-inch strip may fit compact trucks, utility vehicles, and narrow mounting areas better. A rigid or professionally hardwired light bar may offer a cleaner permanent installation, but it usually requires more planning than the TR-04’s adhesive strip and 4-pin connection.
The TR-04 makes the most sense when you want a full-width flexible strip, sequential amber signals, a high LED count, and several functions in one package.
Frequently Asked Questions
Does the Nilight TR-04 fit every truck?
No. Although the listing describes it as a universal-fit 12V accessory, you still need a straight 60-inch mounting path and suitable wiring. Cameras, sensors, step bumpers, trailer plugs, and aftermarket parts may affect fit.
Does every function work through the 4-pin connector?
No. The 4-pin connector handles the standard trailer-light connection, but the white reverse-light function needs the separate reverse wire connected to a suitable 12V reverse-light source. Test the system before mounting the strip.
Can the Nilight TR-04 be cut to fit a smaller vehicle?
The manufacturer does not describe the TR-04 as a cut-to-fit strip. Cutting it could damage the circuits, sealing, and sequential lighting patterns. Choose a shorter model when your vehicle cannot accept the full 60-inch length.
Does it replace the factory brake lights or turn signals?
No. The TR-04 is an additional visibility accessory. Your factory running lights, brake lights, reverse lights, and turn signals should remain functional and clearly visible.
Is the Nilight TR-04 waterproof?
The strip carries an IP67 water-resistance rating and uses flexible silicone construction. Damaged insulation, loose connectors, and unsealed wire splices can still allow moisture into the electrical system.
What comes in the package?
The verified listing includes one 60-inch triple-row light bar, additional mounting hardware, and a user manual. Check the current Amazon package description before ordering because packaging can change.
Does the TR-04 include a remote control?
No remote control is listed. The strip responds to the vehicle’s running, brake, turn-signal, and reverse-light circuits rather than an app or handheld controller.
Who should skip this tailgate light bar?
Skip it when your vehicle lacks a suitable 60-inch mounting area, uses an incompatible electrical system, or cannot provide safe access to the reverse-light circuit. A shorter or professionally hardwired alternative may fit those situations better.
The Bottom Line
The Nilight TR-04 is recommended with caveats for drivers who want a wide, multifunction tailgate light on a compatible 12V vehicle. Its 504 LEDs, six lighting functions, IP67-rated construction, and included mounting supports are useful strengths, while its fixed length and separate reverse-wire requirement are the main limitations.
Buy it when you have enough mounting space and are comfortable confirming the wiring before installation. Skip it when you need a cut-to-fit strip, remote-controlled effects, or a connector-only setup with no additional wiring.
