MAXXHAUL 70205 Trailer Light Kit
The MAXXHAUL 70205 kit includes two 12V LED stop, tail, and turn signal lights, two amber clearance lights, a license plate bracket, and a wiring harness. It’s designed for universal trailer fit and straightforward installation via a 22 ft. split Y-style wiring harness. Best for owners seeking a complete, all-in-one solution with reliable LED performance and long life for frequent use on boats, trailers, campers, or trucks. Caution: verify compatibility with your specific trailer mounting pattern before purchase.
fouwick LED Trailer Lights Kit
This DOT-certified kit uses high-output diodes for bright stop, turn, tail, and side marker functions, with submersible IP67 waterproofing and marine-grade sealing. It includes a longer 25 ft wiring harness (18-gauge copper) and a color-coded split Y-style harness for stable connections. Best for boat trailers or marine applications requiring road legality and enhanced visibility in rain, fog, or night driving. Choose this if you need extended wiring and marine-grade durability; avoid if you require under-80″ width only and stricter aesthetic constraints.
CZC AUTO 12V Submersible LED Trailer Tail Light Kit
Designed for under-80 inch width trailers, these lights offer seven functions including stop, turn, tail, and license plate illumination. They use 18-gauge copper wiring and are fully LED with Sonic Welding Sealing for strong waterproofing. DOT FMVSS108-compliant, making them a solid choice for small to mid-sized trailers, especially boat or utility trailers. Best for budget-conscious buyers who require DOT compliance; avoid if you need wider truck or RV trailer lighting beyond 80 inches.

This kit includes 2 square rear combination tail lights, 6 mini oval side marker lights, a 15.5 inch third brake light bar, and a 25 ft wiring harness with four-flat plug. It covers a wide range of functions—from running and brake to license illumination—making it versatile for campers, utility trailers, and boats. Best for heavy-duty upgrades on mid-sized trailers; better for those needing multiple marker options in a single kit. Note: wiring color codes differ from standard four-flat systems, so plan wiring accordingly.

Best for longer or wider trailers and buyers seeking distinct halo aesthetics with strong waterproofing; choose this if style and conspicuous illumination are priorities, and be aware of the higher price point.
Buying Guide
What to consider when choosing an LED trailer light kit
Trailer width and mounting pattern determine compatibility. Verify under-80 inch or wider compatibility and whether the kit includes all required lights and a license plate bracket.
Waterproofing and durability
Look for IP ratings (IP67 or IP68) and sealing methods such as sonic welding or gasketed lenses. Submersible capability is essential for boat trailers and water-exposed setups.
Wiring and installation
Assess wiring harness length (22 ft vs 25 ft) and harness design (split Y-style). A longer, UV-protected harness helps with longer trailers and harsh sun exposure.
Compliance and safety
DOT/FMVS108 compliance ensures legal road use. Ensure all functions (stop, turn, tail, license plate) are clearly supported and that the kit provides solid illumination in adverse weather.
Functionality and aesthetics
Halo-style lights offer distinctive appearance and glow; standard LED configurations emphasize reliability and bright white light. Consider both functional brightness and the trailer’s look.
