A strong boat trailer light kit pairs submersible 12V lights with the functions and wiring your trailer needs, making it a practical choice for boat owners who launch in and out of the water. The CZC AUTO 12V Submersible Kit leads this roundup with seven listed functions, LED lights, and a copper-wire harness for trailers under 80 inches wide. Other options offer longer harnesses, extra marker lights, or a third brake bar, while some kits are narrower in scope.
Check trailer width, wiring reach, and which lighting components are included before choosing: the products range from basic tail-light sets to expansive kits with multiple clearance lights. The comparison below uses supplied product details, not independent performance testing.
The CZC AUTO 12V Submersible Kit is the best boat trailer light kit in this lineup for typical trailers under 80 inches wide. Its listed seven functions cover stop, turn, tail, reflectors, side marker, and license-plate lighting, and its 18-gauge copper-wire harness is specified for underwater use. It also uses LED diodes rather than incandescent bulbs.
Choose another kit if your trailer is over 80 inches wide or you need a longer harness and extra marker or identification lights.

Detailed Reviews: Best Boat Trailer Light Kit

#1 · Best Overall
1. CZC AUTO 12V Submersible Kit
- Voltage: 12 V
- Lens Material: Plastic
- Weight: 16 oz
Best for: Seven-function narrow-trailer lighting.
Why it ranks #1: Seven listed lighting functions, LED-only diodes, and an 18-gauge copper-wire harness suit boat trailers under 80 inches wide.
Seven functions in the left and right tail lights make the CZC AUTO kit notably comprehensive for trailers under 80 inches wide. Stop, turn, tail, rear and side reflectors, side-marker lighting and license-plate lighting are listed, with LED diodes throughout and an 18-gauge pure-copper wire harness for the installation.
The combined functions give one light assembly several signaling and visibility roles, including license-plate illumination, which can simplify the lighting layout on a narrow trailer. Its 18-gauge pure-copper harness is identified as suitable for underwater operation, matching the submersible kit's boat-trailer use. The 12V package is also listed for utility trailers, trucks and snowmobiles. Because its stated application is under 80 inches wide, that limit should guide selection before wiring begins.
- Seven listed lighting and reflector functions
- 18-gauge pure-copper wire harness
- All diodes are LED, with no incandescent bulbs
- Specified for 12V towing vehicles under 80 inches wide
- Its stated trailer-width application is limited to under 80 inches.
Skip it if you are wiring a trailer over 80 inches wide; Lcrslitx LCX-007 is specifically listed for trailers over 80 inches.
Pick this for a 12V boat or utility trailer under 80 inches wide when multiple reflector and lighting functions in the tail lamps matter. The stated width ceiling makes it a poor match for wider rigs.

- Lens Material: Plastic
Best for: Wide-trailer complete lighting system.
Why it ranks #2: Includes a 25-foot harness, third brake bar, six side markers, tail lights, bracket, hardware, and reflective strips; listed for trailers over 80 inches.
A 25-foot, color-coded four-pin harness and a 13.7-inch third brake light bar distinguish this Lcrslitx kit from basic tail-light sets. Its listed package adds rectangular submersible tail lights, six mini oval side markers, a license-plate bracket, mounting hardware and reflective strips for a broad trailer-light installation.
The long, color-coded four-pin harness provides the listed wiring reach for a larger installation, while the third brake bar adds a separate identification light position. Two IP68 rectangular tail lights handle stop, brake, turn, tail, reverse and license-plate functions; amber and red mini markers add side clearance lighting. The kit is specified for trailers over 80 inches wide and includes mounting hardware and reflective strips, which keeps multiple listed components in one package.

Why it ranks #3: Combines two tail lights, six amber and red side markers, a 13.7-inch brake bar, and a 25-foot harness for a broad installation package.
A 25-foot braided harness with a four-pin plug gives the LIMICAR kit a useful wiring reach for trailer installations, while individually sealed, welding-fused lights are specified for full submersion at boat ramps. The package also includes square tail lights, six side markers, a third brake bar and a license-plate bracket.
The braided 25-foot harness is listed for fully wiring trailers, giving installers a defined cable length and four-pin connection. Individually sealed housings are described as tested for submersion, with fresh- and saltwater use stated for repeated boat-ramp dunking. Two square stop, turn and tail lights work alongside six amber/red markers and a 13.7-inch third brake bar.

Best for: Universal kits for narrow trailers.
Why it ranks #4: Provides two LED stop, tail, and turn lights, amber markers, a bracket, hardware, and a 22-foot split Y-style harness for trailers under 80 inches.
A 22-foot split Y-style, color-coded harness is the key practical feature of this MAXXHAUL kit, giving installers a long, organized wiring run for a trailer-light setup. The package also combines two LED stop, tail and turn lights with amber clearance lights, a license plate bracket and mounting hardware.
The 22-foot split Y harness separates the wiring into a color-coded layout, which can make routing and identifying connections more manageable during installation. Two 38-LED universal tail lights handle stop, tail and turn functions, while the amber side markers add clearance lighting. The kit is specified for trailers under 80 inches wide and uses 12V LED lights; its submersible feature suits boat-trailer use.

#5 · Best IP68-Listed Option
5. LINKITOM 608631397119 Kit
- Voltage: 12 V
- Lens Material: Plastic
- Weight: 16 oz
Best for: Submersion-focused wiring kits.
Why it ranks #5: Its listing specifies IP68 waterproofing and submersibility, plus two tail lights, amber clearance lights, two harness lengths, and a license plate bracket.
Welded lamp housings and a sealed tail-light circuit board give this LINKITOM kit its defining water-focused construction. A drain hole is also specified to let water escape, while the package supplies stop-and-turn LED tail lights, amber clearance lights, two wiring harnesses and a license plate bracket for a trailer-light installation.
The welded lamp construction has no screws on the shade, and the sealed circuit board adds a barrier around the tail-light electronics; together with the drain hole, these details address water exposure on boat-trailer runs. The 22-foot and 4-foot harnesses provide two listed wiring lengths for connecting the kit. It includes reflective stickers and mounting hardware, and its 12V compatibility covers boats, trailers, trucks and buses according to the supplied specifications.
- IP68 waterproof and submersible construction
- Welded lamp housings and sealed tail-light circuit board

6. Nilight TL-22 Light Kit
- Voltage: 12 V
- Lens Material: Polycarbonate
Best for: Seven-function 12V trailer lights.
Why it ranks #6: Lists seven lighting functions for 12V vehicles up to 80 inches wide and includes a two-year warranty, but included kit components are less detailed.
Six lighting and reflector roles are combined in this Nilight kit, covering stop, turn, tail, side marker, side reflector, rear reflector and license-plate light functions. Its listed 12V DC compatibility and 80-inch maximum width frame the fit, while the product description says its LEDs draw less amperage while producing visibility.
Combining the listed functions in the light assemblies can reduce the need to arrange separate lamps for each signaling and reflector role. Nilight specifies a maximum vehicle width of 80 inches and lists boats, trailers, trucks, RVs, tractors and other vehicle types, giving buyers several stated applications to consider. The submersible feature supports a boat-trailer use case, while polycarbonate lenses are specified for the two-piece kit. Confirm that the width limit matches the intended trailer.
- Stop, turn, tail, side-marker and reflector functions
- Includes license-plate lighting
- 12V DC fit for vehicles up to 80 inches wide
- Submersible, two-piece kit with polycarbonate lenses

Consider this for a 12V boat, RV or utility trailer up to 80 inches wide when combined signaling and reflector functions are useful. Its maximum-width specification is the main fit boundary.

9. fouwick LED Trailer Light Kit

- Lens Material: Polycarbonate
Best for: Compact listed-component light kit.
Why it ranks #9: Includes two lights, two amber clearance lights, a bracket, and harness, but supplied details do not establish a specific trailer-width fit.
A compact listed light-body size of 4.6 by 2.6 by 5.1 inches gives this fouwick kit a defined footprint for buyers planning a trailer-light replacement. The 12V package includes two lights, two amber clearance lights, a license-plate bracket and wiring harness, with submersible and waterproof features specified.
The two main lights, amber clearance lamps and license-plate bracket cover several listed positions in one kit, while the wiring harness supports connecting the package to a 12V setup. Polycarbonate lenses are specified, and the product is described as dustproof, waterproof and submersible. Its compatibility list includes boats, trailers, trucks, tractors, buses and dump trucks. Since no width limit or harness length is supplied, buyers should treat those details as unresolved fit considerations rather than assume a particular installation reach.
- Two lights, two amber clearance lights and license-plate bracket included
- Wiring harness included
- 12V submersible, waterproof and dustproof specifications
- Polycarbonate lenses and listed 4.6-by-2.6-by-5.1-inch dimensions

This may suit a 12V boat or utility trailer when the included two lights, amber markers and bracket cover the required positions. The unspecified harness length and width limit matter for planning fit and routing.

#10
10. Wellmax WM51053 Tail Lights
- Voltage: 12 V
- Lens Material: Acrylic
Best for: Stainless-hardware marine tail lights.
Why it ranks #10: The marine-oriented listing includes two 12V LED tail and turn lights with stainless hardware, but does not list a harness or marker-light kit.
Stainless steel mounting hardware and corrosion-resistant materials distinguish these Wellmax marine trailer lights, a focused package of two 12V LED tail and turn signal lamps. Their submersible, waterproof specification supports boat-trailer use, while the stated dimensions give buyers a concrete reference when planning a replacement installation.
The two LED units provide tail and turn signal functions, keeping this package focused on those listed roles rather than a larger set of marker components. Stainless steel hardware and corrosion-resistant materials are specified for marine use, while waterproof and submersible features suit boat-trailer exposure. At 8 by 3 by 23⁄4 inches, the stated light dimensions help assess available mounting space. The product is listed for trailers and boats on 12V systems; no harness is listed among the verified facts.
- Two 12V LED tail and turn signal lights
- Stainless steel hardware included
- Corrosion-resistant materials specified for marine use
- Submersible and waterproof, with stated light dimensions
- The verified package details do not list a wiring harness or marker lights.
Skip it if you need a full kit with a long harness and multiple markers; LIMICAR 200718 includes a 25-foot harness and six side markers.
Choose these for a boat or trailer needing two submersible tail-and-turn lamps with corrosion-resistant materials and stainless hardware. They are a focused light set, so account for the other wiring or marker components your installation requires.

View on AmazonAvoid width and wiring mismatches
Check trailer width and wiring before ordering; a light kit can include useful parts yet still be the wrong fit for your setup. Several products specify compatibility with trailers under 80 inches, including the CZC AUTO 12V Submersible Kit and MAXXHAUL 70205 Light Kit. By contrast, the Lcrslitx LCX-007 Light Kit is specifically described as fitting trailers over 80 inches.
Do not assume those fit statements are interchangeable. Harness length also varies: the MAXXHAUL listing gives a 22-foot split Y-style harness, while the Lcrslitx LCX-007 provides 25 feet.
LINKITOM models list a 22-foot harness plus a separate 4-foot harness. These descriptions do not confirm every connector or routing layout, so compare the included wiring with your trailer and verify connector compatibility before installation.
Plan for water exposure and maintenance
Repeated immersion makes sealed construction and post-launch checks relevant, but a waterproof label alone does not establish how a particular installation will fare. LINKITOM describes welded lamp construction, sealed circuit boards, drainage, and IP68 protection; LIMICAR lists individually welded-sealed lights and IP67 submersibility. MAXXHAUL and Wellmax also describe their kits as submersible, without the same IP rating in the supplied facts.
Water exposure can reveal a weak connection or damaged wire even when the lamp itself is sealed, so inspect wiring connections and grounds if a light fails after launching. The product descriptions do not specify connector sealing for every kit.
Treat the housing and the wiring connection as separate parts of the installation, and follow the manufacturer’s installation instructions rather than assuming a submersible lamp makes every connection waterproof.
How to Choose a Boat Trailer Light Kit
Trailer width and fit
Start by matching the kit’s stated width fit to your trailer, rather than assuming universal wording covers every size. The CZC AUTO 12V Submersible Kit, MAXXHAUL 70205 Light Kit, and Nilight TL-22 Light Kit list fit for trailers or vehicles up to or under 80 inches. The Lcrslitx LCX-007 Light Kit is described for trailers over 80 inches.
Several other listings say they fit boats or trailers but do not provide a width threshold in the supplied details. Buyers with a measured trailer under 80 inches can prioritize the specifically stated under-80 options; owners of wider trailers should examine the LCX-007 fit description and verify mounting dimensions before ordering.
Harness length and included wiring
Choose a harness length that can reach your lights along your trailer’s actual routing path. The MAXXHAUL 70205 Light Kit lists a 22-foot split Y-style color-coded harness; LINKITOM kits list 22-foot and 4-foot harnesses; and the Lcrslitx LCX-007 Light Kit and LIMICAR 12V LED Light Kit list 25-foot harnesses. These figures are not a guarantee of fit because routing and trailer layout vary.
If your trailer is long or the wire must follow a circuitous route, the listed 25-foot harness offers more stated length than the 22-foot option. For a shorter setup, a more modest harness may be sufficient, but confirm plug type and wire routing first.
Lighting functions and kit contents
Compare the functions and extra components you need, not just the number of lights. The CZC AUTO 12V Submersible Kit lists seven functions, including stop, turn, tail, reflectors, side marker, and license-plate lighting. The Lcrslitx LCX-007 Light Kit goes further in package contents, listing a third brake bar, six mini oval markers, a bracket, hardware, and reflective strips.
MAXXHAUL 70205 Light Kit includes two tail lights, two amber markers, a bracket, wiring, and mounting hardware. Buyers replacing a simple set may prefer a basic package; those building out a trailer or seeking additional marker coverage may favor the more component-rich kits.
Check that each listed function and part suits your trailer’s requirements.
Which Boat Trailer Light Kit Should You Choose?
For most boat trailers under 80 inches, choose the CZC AUTO 12V Submersible Kit: it combines seven listed functions with LED lights and an 18-gauge copper-wire harness. If your trailer is over 80 inches and you want a broad package, consider the Lcrslitx LCX-007 Light Kit, which lists a 25-foot harness, third brake bar, and six side markers. For added marker coverage plus a long harness, the LIMICAR 12V LED Light Kit includes six markers and a 25-foot harness.
The MAXXHAUL 70205 Light Kit is a more straightforward under-80-inch option with a 22-foot split harness and mounting hardware. If your priority is an IP68-listed option, compare the LINKITOM 608631397119 Kit and verify the wiring and fit for your specific trailer.

Frequently Asked Questions
How do I check whether my trailer uses a four-pin or another wiring connector?
Count the contacts in the trailer-side plug and compare its shape with the connector on the towing vehicle. A four-pin connector has four contacts; other connector types have different contact arrangements. Check the trailer and vehicle manuals or wiring diagrams before buying, and confirm whether an adapter is needed.
What should I do if trailer lights stop working after a boat launch?
Start by checking the connector, ground, and visible wiring for looseness, corrosion, damage, or moisture, then test each light function. Disconnect power before inspecting or repairing wiring. If the problem persists, consult the kit instructions or a qualified technician; do not assume a light is safe to use until it works reliably.
How can I tell whether my trailer needs lights mounted farther apart or higher?
Compare the trailer’s width and light positions with the applicable local lighting requirements, then check that the lights are visible and unobstructed from behind. Requirements can vary, so measure your trailer and consult local rules rather than relying on a kit label alone. Choose a layout that fits the trailer and its mounting points.
How do I know whether a light kit’s harness is long enough?
Measure the wiring route on your trailer from the connection point to each light, following the path the harness will take. Compare that measurement with the harness length listed for the kit, allowing for routing and attachment. If the length or layout is not specified, confirm it before purchase rather than assuming it will fit.
What should I check before installing a replacement light kit?
Confirm that the kit’s connector, wiring arrangement, light locations, and mounting method suit your trailer. Check the product details for listed functions and any width guidance, and compare them with your trailer’s existing setup. Follow the installation instructions, then test the lights before towing to verify that each function works.
Final Words
For most boat trailers under 80 inches wide, the CZC AUTO 12V Submersible Kit is the strongest fit here, with seven listed functions, LED diodes, and an 18-gauge harness specified for underwater use. For a trailer over 80 inches, consider the Lcrslitx kit’s listed long harness and additional lights. Compare harness reach and mounting layout, and verify connector compatibility before choosing.
