Partsam 12V Submersible LED Trailer Light
The Partsam unit offers a dual-branch design with 15 diodes for one side and 19 diodes for the other, providing multiple functions: stop, turn, tail, and license illumination. It is suitable for trailers under 80″ and serves both curb and street sides with different function sets. Best for buyers who want flexible wiring and a compact, all-in-one solution. A potential limitation is that wiring and mounting require careful alignment to ensure all functions activate correctly.
Wellmax 12V LED Trailer Lights
The Wellmax kit includes two submersible LED tail lights with stainless hardware, designed for long-term use in harsh weather. The lights are fully sealed to withstand inclement conditions and DOT FMVSS108 compliant, aiding visibility and reducing liability. Best for buyers seeking a ready-to-install, corrosion-resistant pair. A caveat is limited expansion options beyond the included two-light setup.
CZC AUTO 2PCS Submersible Under 80″ Lights
These CZC AUTO lights are a two-light under-80″ kit featuring 18-gauge copper wiring and full sealing technology. The left and right units provide seven functions, including license plate illumination. They are designed for easy underwater operation and are DOT standards-compliant. Best for buyers who want a robust, plug-and-play pair with strong waterproofing. Limitation: installation details like mounting angles must be observed to avoid water intrusion.
LINKITOM New Submersible LED Trailer Light Kit
The LINKITOM kit features halo-style stop/turn lights, two amber clearance lights, and long wiring harnesses. It is IP68 waterproof and totally welded, with a dedicated drain hole to expel water and protect diodes. Best for buyers who want a premium look with distinct halo lighting and comprehensive wiring. Choose this if you need higher-end aesthetics and a sealed circuit; avoid if you require a compact two-light option.
WoneNice LED Trailer Light Kit
The WoneNice kit provides a complete set: two brake/turn/tail lights, two amber clearance lights, and a 25-foot wiring harness with license plate bracket. IP67 waterproofing and a long LED life of up to 50,000 hours are highlighted. Best for buyers who want a full, ready-to-install pack with good longevity. A limitation is that IP67 is slightly less protective than IP68 in extreme water exposure environments.
Lcrslitx Submersible LED Trailer Light Kit
This kit combines stop, tail, turn, side marker, and license plate lights in a marine-grade IP67 design with a 25-foot wiring harness. It is DOT compliant and emphasizes brightness for signaling. Best for buyers needing a robust all-in-one option for trucks or utility trailers under 80″. Limitation: 25-foot harness may be longer than necessary for smaller trailers, requiring extra routing effort.
Buying Guide
What should I consider before buying trailer lights?
Trailer width compatibility is essential. Look for lights rated for under-80″ trailers if that matches your setup. Waterproofing level matters; IP68 is the strongest submersion rating, while IP67 offers solid protection with a slightly lower rating.
DOT compliance and safety
Choose DOT-compliant lighting to ensure visibility and reduce liability. Verify that the kit covers brake, turn, tail, and license plate illumination for full signaling functionality.
Installation and wiring
Consider whether the kit includes a full wiring harness, mounting hardware, and license plate lighting. Durable copper wiring and sealing technologies reduce corrosion risk in marine environments.
Durability and longevity
Submersible LEDs with corrosion-resistant housings extend service life in wet climates. Look for SONIC or welding-seal technologies as indicators of solid construction and water-tight integrity.
Installation environment
For boats and saltwater exposure, submersible, fully sealed units are preferable. Drain holes and water-expulsion features help prevent water buildup inside the housing.
Budget and future-proofing
Two-lamp kits are adequate for basic towing needs, while halo or multi-function units offer aesthetic and signaling advantages. Consider future trailer upgrades when selecting a kit.
