Our Picks at a Glance
How To Choose The Best Truck Trailer Lights
Your choice hinges on towing frequency and installation effort.
Wired vs. Wireless: The Core Decision
Your first choice is between permanent, hardwired lights and temporary, magnetic wireless ones. Hardwired lights are the traditional, most reliable route for a trailer you own long-term, offering a permanent solution that’s always ready. Wireless kits are a brilliant option for occasional towing, multiple trailers, or rental situations, as they mount in seconds without any wiring.
Waterproofing and Durability
Consider the weather. Look for an IP67 rating, meaning the light is fully protected against dust and can handle temporary immersion in water. This is ideal for boat trailers. A lower IP65 rating means it’s water-resistant and fine for rain but shouldn’t be submerged. For wired options, think about the lens material—polycarbonate is a tough, impact-resistant plastic that stands up to road debris.
LED Brightness and Count
More LEDs usually mean a brighter, more evenly lit surface. A light with 40 individual LEDs will generally outshine a 24-LED model, which is crucial for visibility in bright sunlight. Also, check for special features like integrated reflex reflectors, which are required on trailers wider than 80 inches, and reverse light functions for extra safety when backing up.

In-Depth Reviews
1. Partsam 2Pcs Double Trailer Tail Lights
Our pick — over 4.5★ from 750+ verified ratings; the strongest balance of quality and price.
The complete, bright, plug-and-play package for anyone replacing old camper or trailer lights.
The stand-out feature here is the dual-lens design: a red lens handles your stop, tail, and turn functions, while a separate clear lens is dedicated to backup lighting, all in one slim assembly. This means you get full functionality without needing a separate reverse light, and the built-in reflex reflector removes the need for an additional reflector on many setups. At just 0.87 inches thick, it keeps a low, clean profile on your trailer’s rear.
Installation is straightforward with 5 wires: white for ground, blue for backup, red for stop/turn, and black for running lights. The package is complete with stainless steel screws and gaskets to create a secure, cushioned seal. Most owners find the brightness a massive upgrade, and one buyer captured the sentiment perfectly, reporting: “Now nobody can tell me they cannot see my blinkers. Wow. What a big difference.”
You can mount this on trailers, RVs, trucks, tractors, buses, or heavy trucks, and it measures 9.5 inches long overall. Most buyers get a smooth install, but if you’re switching from halogen bulbs, you may need resistors (small electrical parts that manage current) to stop hyper-flash—when your turn signals blink too fast.
What Makes It a Winner
- Dual-lens design (red & clear backup) in one slim, 0.87-inch thick unit
- Complete kit: includes stainless steel screws & mounting gaskets
- One owner says their blinkers are now impossible to miss
Fit & Installation Notes
- Requires a 9″ x 6.3″ cutout for installation
- May need resistors if upgrading from halogen bulbs to avoid hyper-flash
The complete upgrade: This is the best choice for RV and trailer owners who want a single, high-performance unit that handles stop, tail, turn, and backup functions without extra parts.
Think twice if: Your trailer has a non-standard wiring setup that uses a shared brake and turn signal, as this requires separate inputs.
2. 4Pcs 4 Inch Round LED Trailer Tail Lights
A four-pack of bright, easy-fit round lights that solves all your trailer’s lighting needs at once.
You get four 4-inch lights in this package, making it a complete solution for a standard trailer that needs two rear lights plus side markers or spares. Each one packs 24 LED chips, which draw less current and shine brighter than old incandescent bulbs. They’re rated IP65 waterproof, so they’re ready for rain and road spray, but you should avoid fully submerging them.
The flush-mount design is tidy, and the kit includes round rubber grommets and 3-prong wire pigtails for a clean, standard connection. One owner’s assessment is spot-on: “Great fit, value, quality, brightness, and function. They check all the boxes.” Wiring is simple too—white is ground, red is high brightness, and black is low, so you can use them for brake, tail, turn, or running light functions.
A practical installation tip from a buyer: use soapy water on the rubber ring to make it slip into the drilled hole easily. Just remember you’ll need to drill a hole about 4.6 inches to fit them.
The value leader: Owners consistently praise the build quality and how easily they swap in as replacements, with many calling them a perfect fit for a fraction of truck-stop prices.
Know the limits: The IP65 rating means they’re not designed for submersion, so boat trailer owners who regularly dunk their rigs should look at the higher-rated IP67 options.
3. Nilight 4″ Round Trailer Tail Light
A simple, sturdy 2-pack with impressive waterproofing and easy bracket mounting.
Don’t let the lower 12-LED count fool you; these use 12 high-quality 3030 SMD LED chips, which are known for a wider lighting angle and better heat dissipation. This translates to a light output the maker claims is high, making it a top performer in its class. You get high brightness for turn/brake signals and lower brightness for the tail light function.
Mounting is a breeze with the included metal brackets, which have a powder-coated finish to resist rust. The unique grommet design has upgraded notches and bulges that create a tighter, shake-proof fit between the light, grommet, and bracket. This means no worries about the light or wires coming loose on the road.
For weather protection, the Nilight carries a strong IP67 waterproof rating and is highly silicone-sealed, making it ready for harsh weather. This model has a 0.39-inch round hole diameter, so be sure to check the hole size on your trailer before purchasing.
Built to last: You get an IP67 seal (fully dust-tight and protected against temporary water immersion), a polycarbonate lens (a tough, impact-resistant plastic), and a rust-resistant bracket, so it holds up in rain, snow, and road salt without failing.
Simplest setup: If you don’t want to drill a new hole and your trailer has a standard 0.39-inch mount, this is a true bolt-on upgrade.
4. Partsam 17″ 40 LED Light Bar
A wide, powerful light bar that doubles as a brake light and a clearance marker for extra visibility.
This pack of two 17-inch light bars is a powerhouse, using 40 high-power Super FLUX LEDs arranged in two rows for a bright and even output. At 40 LEDs versus the 24-LED 4-inch round lights, this bar is ideal for illuminating a wide area. Buyers report it lights up everything under the truck from the front bumper, showcasing its impressive brightness.
Beyond the brake and tail light function, you can mount this bar on the top of your trailer as a clearance ID light, which is a requirement for trailers measuring 80 inches or wider. The chrome plastic bezels dress it up nicely and give it a clean, finished look. The wiring is standard, with a white ground, black tail light, and red brake light.
Installation is manageable: you bolt it down using the supplied hardware and add silicone caulking to keep water out of your trailer. It’s rated IP65, so it can handle rain, but like the 4-inch rounds, it shouldn’t be used under water.
The visibility upgrade: The sheer width and 40-LED count make this the best pick for making a wide trailer or truck bed unmistakably visible, especially in poor light.
Reliability caveat: Some owners have noted that while the light is bright, the longevity can be inconsistent, with occasional units failing; always check your wiring to avoid crossfeed issues.
5. 2Pcs 6″ Smoked Lens Oval LED Trailer Lights
Smoked-lens style meets serious submersible durability and 52 ultra-bright LEDs.
These 6-inch oval lights make a statement with their smoked lens, giving any truck or trailer a sleek, custom look. One owner even bought a second set for other trailers after seeing how they looked on their black flatbed. The style doesn’t compromise function, as the 52 red LEDs provide intense brightness for braking and turning, while a distinctive halo light effect handles the running light.
Beyond the looks, this is a rugged, seriously waterproof unit. It carries an IP67 rating and is sealed with a gluing process that makes it submersible, with UV protection to prevent lens fading. This makes it an excellent choice for boat trailers or any rig that faces harsh weather or water crossings.
The package includes rubber grommets and 3-wire plugs for a standard connection. Owners mention the fit is perfect and they’re easy to wire up. The only minor note from a reviewer was that the rubber inlet could be a bit thicker, but this doesn’t detract from the overall quality and value.
Form and function: For a custom look without sacrificing durability, this smoked-lens pick delivers superior heat-resistant quality that owners say feels better than OEM parts.
Check your plug: While the 3-pin plugs are standard, a few owners noted they can feel slightly loose, so a zip tie or a bit of tape for extra security is a common safeguard.
6. TXGSDXS Magnetic Wireless Trailer Lights
A versatile magnetic kit that installs in 30 seconds and works with multiple trailers.
This wireless kit suits multi-trailer owners who need quick, tool-free setup. You simply plug the 7-way receiver into your truck, stick the magnetic lights on the back of whatever you’re hauling, and pair them by holding the power button. You’re ready to go in about 30 seconds, with no wiring or permanent mounting involved.
The included magnetic mounts are strong, and the lights charge via USB-C. A full charge takes just 2.5 hours and gives you 10 hours of use, which covers even the longest hauling days. The signal operates on a 2.4GHz frequency with an effective range of over 100 feet (30.5 meters), ensuring the lights stay synced with your truck’s signals.
They function as turn signals, driving lights, brake lights, hazard lights, and even a license plate light. They’re built with a shockproof housing for all-weather towing. Just be aware this kit isn’t suitable for vehicles that use a shared wiring interface for brake and turn signals, as it has a separate input for the brake function.
Instant flexibility: Perfect for renting a trailer occasionally or towing a jeep behind a motorhome, providing safe towing “without the hassle of plugging in wires,” as one owner put it.
Consider the magnet: While effective, the padding on the magnet can detach, and a few owners recommend adding a safety tether for extra security on rough terrain.
7. Agrieyes T312 Wireless Trailer Lights
A premium wireless kit packed with features like a reverse light and an adjustable, scratch-proof mount.
The Agrieyes T312 steps up the wireless game with a thoughtful feature set. The rubber-coated, adjustable magnetic base is a standout, designed to prevent scratches and hold firm at speeds tested up to 50 mph. The base is also articulated, so you can angle the light head to suit your trailer’s shape perfectly.
It uses ceramic base bulbs, which offer superior brightness and heat dissipation. The maker claims one-mile visibility, backed by LEDs rated for 60,000 hours. Integrated retroreflectors enhance safety from all angles, and the added reverse light function is a practical bonus for backing up in the dark.
It charges via USB-C in 2.5 hours for 9 hours of use and boasts an IP67 waterproof rating. The kit operates in temperatures from -23°C to 65°C, so it’s built for extreme weather. It’s a favorite for saving the cost of rewiring an old trailer, with owners praising how bright it is and how easy the setup is.
Feature-forward: The combination of a reverse light, adjustable angle, and one-mile visibility makes this the most capable wireless kit for a variety of trailers and boats.
Setup can be finicky: The sync process can take a few minutes to get right, and while the magnets are strong, some owners have reported instability on very rough, high-speed roads, so a safety cable is wise.
8. NeaLia 110° Rotatable Magnetic Wireless Lights
A rotatable, premium wireless tail light kit that eliminates wiring corrosion for good.
The defining feature of the NeaLia kit is its 110° rotatable metal bracket, allowing you to set the light at any free angle. This makes it perfect for flatbeds, horse trailers, or hay bales where the mounting surface might not be perfectly vertical. It even includes 2 spare iron plates specifically for aluminum trailers that magnets won’t stick to.
It eliminates corroded-wiring issues, ideal for saltwater boat trailers. The wireless design completely removes the constant battle with rust and bad connections. This DOT/FMVSS 108-certified kit offers 5 modes: running, brake, left turn, right turn, and reflex reflector.
Charging is fast via a USB-C port, with a full charge in 2.5 hours and a 9-hour battery life. The housing is tough, made from premium PC, metal brackets, and ABS material, with an IP67 waterproof rating to stand up to dust, dirt, rain, snow, and fog.
Angle it your way: The unique rotatable bracket is a real problem-solver for unusual trailer builds, and owners love eliminating wiring gremlins on their boat trailers.
Magnet strength varies: While many find the magnets strong, a consistent theme is that they work best on clean steel; the suction cup add-on is less reliable at speed, so hard-mounting may be needed for rough use.
9. ZUNAICE Adjustable Magnetic LED Trailer Lights
A premium, durable wireless kit with industry-leading LED lifespan and powerful magnetic hold.
The ZUNAICE kit is built for the long haul, using rugged ceramic-based LEDs that boast a 60,000-hour lifespan. This durability pairs with 1.5-mile visibility for long-distance safety. The 2.4GHz wireless connection is stable for over 100 feet, and the built-in antenna ensures a reliable link with your transmitter.
The magnetic base and suction cup hold the light securely up to 50 mph without it coming off, so you can trust it on the highway. If your trailer surface is wood or aluminum (which won’t hold a magnet), you get an iron mounting plate and screws to attach it instead. Customers note the magnets are “super strong” and the lights stay put at freeway speeds, though many still add zip ties for extra security.
It offers 5 lighting modes, including running, turn signals, brake, reverse, and warning lights. The kit is IP67 waterproof and operates in a wide temperature range from -40°F to 149°F. It even comes with a transmitter featuring both 7-pin and 4-pin standard connectors, ensuring compatibility with most trucks.
The long-distance choice: With 60,000-hour LEDs and a -40°F to 149°F operating range, this is the most sturdy premium wireless pick for harsh climates.
Less adjustable: The main trade-off is that the magnet mount limits angle adjustability, requiring removal and a tool to change the direction of the light.
Understanding the Specs
IP Ratings (IP67 vs IP65)
The IP (Ingress Protection) code tells you how well a light is sealed against dust and water. An IP67 rating means it’s fully dust-tight and can withstand temporary immersion in water (up to 1 meter for 30 minutes). An IP65 rating means it’s dust-tight and protected against low-pressure water jets from any direction, making it rain-proof but not submersible. For boat trailers that get dunked, hunt for IP67.
LED Count & Output
The number of LEDs (Light Emitting Diodes) directly influences brightness and how evenly light is spread across the lens. More LEDs, like the 40 in the Partsam bar, usually mean a more intense and uniform glow compared to a 24-LED light. This is what makes your trailer visible in bright sunlight, and it’s a key difference between a cheap replacement and a high-performance safety upgrade.
