CZC AUTO 12V Submersible LED Trailer Tail Light Kit
This kit provides left and right tail lights with seven functions: stop, turn, tail, rear reflector, side reflector, side marker, and license plate light. It is designed for trailers under 80 inches wide, including boat and utility trailers. The 18-gauge copper wiring offers underwater performance, and the elements are LED-only to minimize corrosion and burn-out risks. It carries DOT FMVSS108-style compliance signals through robust construction, including sonic welding sealing technology that protects gaps and wire entries from water intrusion.
Best for: boat trailers and small utility trailers needing a compact, corrosion-resistant kit with integrated license plate lighting. Why selected: strong waterproofing, multi-function output, and marine-grade sealing support long life in wet environments.
Caution: Some installations may require precise alignment of license plate lighting to maintain visibility at the back of the trailer.
Wellmax 12V LED Trailer Lights
Wellmax offers a low-profile, submersible LED tail light kit with two 12V lights and stainless steel mounting hardware. Built for long-term use, the lenses are acrylic to block water, while the LEDs provide high visibility in adverse weather. The kit is fully DOT FMVSS108 compliant, ensuring visibility, durability, and legal compliance to reduce liability concerns for operators. The design emphasizes corrosion resistance for frequent exposure to saltwater and splash.
Best for: boat owners and campers seeking a compact, weatherproof kit with durable hardware and clear compliance. Why selected: high visibility, strong submersion protection, and straightforward mounting for quick upgrades.
Caution: Some users may prefer a kit with a dedicated third brake-light integration if required for larger trailers.
Partsam 12V Submersible Square LED Trailer Light
Partsam’s square LED lights are designed with two version options: a red/white dual-LED setup delivering multiple functions and a more expansive third-light version with extra illumination for license plate visibility. The left side supports six functions; the right side adds additional lighting, such as the license plate light. This configuration is useful for trailers under 80 inches, boats, trucks, and campers. The IP68 rating ensures submersion protection in wet conditions, and the design aligns with DOT compliance to maximize road safety.
Best for: buyers needing a flexible 2-sided setup with robust function coverage for smaller trailers. Why selected: clear separation of left/right functions and license illumination in a modular form.
Caution: The two versions differ in function counts; verify the exact wiring and lens configuration before purchase for your trailer.

The kit is designed for boats, utility trailers, RVs, campers, and trucks under or over 80 inches. It uses IP67 sealing to endure marine environments and salt spray, plus a dual-brightness system to differentiate running lights from braking signals. DOT compliance is highlighted for safety and legal use, with LEDs delivering higher efficiency and faster response than incandescent bulbs.
Best for: those seeking a complete, all-in-one kit with a long wiring harness and marine-grade protection. Why selected: comprehensive lighting package with clear, color-coded wiring for straightforward installation.
Caution: The included third brake-light bar may be an over-spec for very small trailers; ensure compatibility with your trailer design before installation.

Buying Guide: Key Considerations For Boat Trailer Lights
- Waterproofing and submersion: Prioritize IP68 or IP67 ratings for boat trailers and frequent water exposure.
- DOT compliance: Look for FMVSS108 compliance or equivalent certification to ensure legal and safe operation.
- Function coverage: Ensure the kit includes stop, turn, tail, marker lights, and license plate lighting unless you only need basic signaling.
- Wiring and harness length: Check harness length to fit your trailer length; longer is often helpful for larger trailers.
- Durability: Corrosion resistance and marine-grade sealing extend life in saltwater or splash-heavy environments.
- Installation: Consider whether included hardware, clear wiring diagrams, and color-coded wiring simplify the process.
- Size compatibility: Confirm under-80″ and over-80″ trailer compatibility to avoid mismatches with your rig.
