The passenger-side assembly provides six functions—stop, turn, tail, rear reflex reflector, side marker, and side reflex reflector—plus a license plate illumination option on the street-side unit. The curb-side unit includes 19 diodes for enhanced visibility. The lights claim IP68 submersibility and universal applicability for trailers under 80 inches, trucks, boats, and more. Wiring simplicity and reflector integration support quick installation on a wide range of trailers and recreational equipment.
Nilight TL-01 6″ Oval LED Tail Lights (2-Pack)
Nilight TL-01 units combine brightness and reliable mounting with 10 high-quality SMD LEDs per light. They’re designed for surface mounting with included grommets and a three-prong plug for weatherproof connections. The unique design features “ears” on the sides to improve attachment and stability within the grommet, helping resist loosening on rough roads. These lights offer strong turn/brake signals and clear tail lighting, contributing to safer nighttime visibility for trailers, RVs, Jeeps, and pickup trucks.
Wellmax 12V LED Trailer Lights
The Wellmax kit emphasizes submersibility and long-term durability. The two 12V LED tail/turn lights come with corrosion-resistant hardware for secure mounting. The acrylic lens design helps to block water ingress, protecting circuits during travel in inclement weather. The lights are fully compliant with DOT FMVSS108, aiming to help ensure visibility, reliability, and reduced liability in the event of a mishap. Bright, clean LEDs improve signaling for drivers behind you, especially in wet conditions or at night.
MAXXHAUL 70205 Trailer Light Kit
This all-in-one kit includes two 12V LED tail/turn lights, two clearance lights, a license plate bracket, and a wiring harness with a 22-foot, color-coded Y-style connector. The kit is designed for broad trailer compatibility and aims to simplify installation with a complete electrical package. Its LED technology provides bright signaling with extended longevity compared to incandescent lighting. This is a practical option for boat trailers, utility trailers, and RV setups where a full lighting solution is preferred in one purchase.
CZC AUTO 12V Submersible Left & Right Lights
CZC AUTO’s dual-light setup covers multiple functions with a left light that includes license plate illumination, and a right light with standard tail/stop/turn features. The design emphasizes full reflector integration and waterproof sealing (IP68), plus 18-gauge copper wiring to ensure sturdy underwater performance. DOT-standard-compliant testing is noted, making these a solid option for boat trailers and recreational trailers where durable, all-in-one lighting is desirable for watercraft transport and heavy-duty use.
CZC AUTO 12V Submersible Trailer Lights (Under 80 Inch)
This CZC AUTO pair focuses on multi-function LED performance with six common functions (Stop, Turn, Tail, rear reflector, side reflector, side marker) plus a left-light license plate feature. Built for under-80-inch trailers and similar towing configurations, the system emphasizes waterproofing via Sonic Welding, edge-sealing, and robust 18-gauge copper wiring. The emphasis on all-LED diodes avoids incandescent components, aiming for higher visibility, longer life, and better weather tolerance in marine and terrestrial trailer applications.
Buying Guide: Key Purchase Considerations
- Waterproofing and submersion: Look for IP ratings such as IP68 and fully sealed designs. Submersible lights perform better in boats, snowmobiles, and trailers that encounter splashes or rain.
- Multi-function capability: Ensure the kit provides required functions (Stop, Turn, Tail, License Plate, Reflectors) for your trailer and complies with local regulations.
- Wiring and installation: Check whether the kit uses a simple three-wire connection or requires more complex harnesses. Surface-mount vs. recessed mounting and included grommets affect installation ease and stability.
- Durability and materials: Corrosion-resistant housings, rugged lens materials, and robust mounting hardware extend life in harsh environments.
- DOT/FMVTSS108 compliance: For road-use trailers, DOT-compliant or FMVSS108-aligned products help ensure visibility, reliability, and legal compliance in many jurisdictions.
- Size and compatibility: Trailer width and mounting hole patterns matter. Measure lens dimensions and confirm that grommets or brackets fit your trailer’s frame.
- Electrical longevity: LED diodes typically outlast incandescent bulbs, but choose lights with good heat dissipation and sealed wiring to avoid moisture-related failures.
- Replacement and availability: Consider brands with readily available replacement lights and accessories (license plate lights, reflectors, wiring kits) to simplify maintenance.
The five options above cover a spectrum of needs—from compact, high-visibility oval units to comprehensive kits with license-plate illumination and full multi-function capabilities. When selecting, prioritize compatibility with your trailer’s size, anticipated weather exposure, and the level of maintenance you’re prepared to perform. For fleet operators or frequent travelers, opting for DOT/FMVTSS108-compliant, submersible lights with sturdy housings and dependable mounting hardware can reduce downtime and improve road safety across trips.
