Lcrslitx Boat Trailer Light Kit
This complete kit includes two IP68 submersible rectangular tail lights, a 13.7″ 3rd brake light bar, four amber and two red side marker lights, a 25-foot four-pin wiring harness, license plate bracket, mounting hardware, and reflective tape. The left tail light provides a dedicated license plate lamp, enhancing rear visibility. Best for trailers over 80 inches in width that require full lighting coverage and a central stop light. While the kit offers robust waterproofing and fast-responding LEDs, it is a larger investment compared to basic configurations.
Who this is best for: Boat, utility, enclosed, flatbed, horse trailers, campers, RVs, and snowmobiles that exceed 80″ width and seek an all-in-one solution with a 3rd brake light. Why selected: it integrates a complete set with a dedicated license plate lamp and dual-brightness wiring for running and brake functions, delivering comprehensive coverage in a single kit.
Caution: Requires careful wiring to ensure correct color-coding for running, brake, and reverse signals; verify mounting positions to avoid obstructing license plate illumination.
CZC AUTO 12V Submersible Trailer Tail Light Kit (Under 80″)
- Left and Right lights offer seven functions: stop/turn/tail, rear reflector, side reflector, side marker, and license plate light.
- 18-gauge copper wiring and full LED diodes provide underwater-friendly illumination.
- DOT FMVSS108-certified components with sonic welding for water resistance.
Best for: smaller trailers under 80″ that still require reliable, fully integrated LED lighting with waterproof construction. Why: DOT compliance and strong waterproofing help minimize water exposure risks on boat trailers. Limitation: designed for narrower trailers, so wider configurations may require alternatives.
Note: This kit emphasizes underwater-resistance and high visibility, making it a strong match for frequent water launches. Avoid if you need a 3rd brake light or extensive marker lighting beyond a standard setup.
MAXXHAUL 70205 Trailer Light Kit
This universal kit includes two 12V LED stop/tail/turn lights, two amber clearance lights, a license plate bracket, and a wiring harness. It’s designed for easy installation with a 22-foot split Y wiring harness. LEDs offer longer life than incandescent counterparts and are suitable for a wide range of trailers including boat, utility, and camper setups.
Best for: Budget-minded buyers who need broad compatibility and straightforward installation for multiple trailer types. Why selected: the comprehensive package and split wiring harness simplify mounting on many trailers. Caution: features are basic relative to higher-end kits with extra lighting bars or halo effects.
LINKITOM Submersible LED Trailer Light Kit
This HALO-style kit features two stop/turn LEDs with a distinctive halo glow, two amber clearance lights, and two wiring harness options (22 feet and 4 feet). It’s IP68 waterproof and fully welded for submersion tolerance. DOT-compliant materials and corrosion-resistant ABS housing support durable outdoor use. The drain hole design helps water drainage to prevent moisture buildup.
Best for: Trailers that benefit from high-visibility halo lights and a robust wet-environment seal. Why selected: the halo design adds distinctive visibility and the kit emphasizes water resistance for marine environments. Caution: halo lighting aesthetics may differ from classic trailer lighting expectations.
CZC AUTO 12V LED Low Profile Submersible Kit
Two combination running/stop/tail/turn lights with a license plate bracket and a 25ft four-pin wire harness. The kit upgrades to 18 AWG copper wiring for underwater performance and claims waterproof/submersible testing. Left and right lights use different diode counts to support full functionality, with a DOT-standard design for on-road legality.
Best for: Trailer owners seeking a low-profile yet fully functional LED kit for boat or utility trailers under 80″. Why selected: strong waterproof testing notes and DOT support; the kit emphasizes compact design without sacrificing function. Caution: ensure correct diode function alignment during installation to preserve signal accuracy.

Buying Guide: Key Considerations for Boat Trailer Light Kits
- Trailer width compatibility: Most kits list suitability for under 80″ or over 80″ trailers. Measure your trailer to ensure proper fit and mounting.
- Waterproofing and submersion readiness: IP ratings (IP67/IP68) and welded housings improve reliability in splash zones and during launches.
- Lighting functions: Look for kits that provide running, brake, turn, tail, license plate illumination, and side reflectors to meet DOT requirements.
- Wiring harness length and quality: A longer wiring harness offers flexibility for longer trailers; check harness gauge and copper content for durability in marine environments.
- Installation complexity: Some kits include all mounting hardware and plates, simplifying installation; others may require additional brackets or drilling.
- Compliance and safety: DOT FMVSS108 certification ensures the kit meets U.S. highway safety standards for trailer lighting.
- Durability in harsh conditions: Look for shatter-resistant lenses, UV protection, and corrosion-resistant housings suitable for saltwater use.
FAQ
- What is the difference between IP67 and IP68 for trailer lights?
IP67 means water protection up to 1 meter for 30 minutes, while IP68 indicates deeper immersion and longer exposure; IP68 is generally better for boat trailers that launch into water. - Do I need a DOT-compliant trailer light kit?
DOT FMVSS108 compliance helps ensure your trailer lighting meets U.S. safety standards for road use and can affect legality in many states. - Can I install boat trailer lights without professional help?
Yes, many kits are designed for DIY installation with basic hand tools, but follow wiring color codes and mounting instructions carefully to avoid shorts. - Are LED trailer lights more reliable than incandescent ones?
LED lights typically offer longer life, faster response, and better visibility in varied weather, while consuming less power in many setups. - What should I do if a light stops working after launch?
Check the wiring harness connections, verify ground continuity, and inspect the seal around the light housing for moisture ingress.
