Buying Guide: Submersible Trailer Lights
What matters most when selecting submersible trailer lights is a balance of waterproofing, signal coverage, and ease of installation. Prioritize lights with DOT compliance to ensure federal visibility standards and liability protection. Consider the trailer width and whether you need a multi-function setup (stop, tail, turn, license plate) or a focused pair of lights. For marine use, ensure the seals and gaskets resist saltwater corrosion. Larger kits may be preferable for wider trailers to maintain even lighting along the vehicle’s length.
Key purchase considerations
- Waterproof rating: IP68 is common in marine-grade setups; submersible performance depends on seals and drain design.
- Functionality: Decide between two-light pairs or full multi-function sets with license plate illumination.
- Wiring: Confirm harness length and wire gauge (18 AWG vs 16-18 AWG) for marine reliability.
- Diameter and fit: Ensure lights fit within the trailer’s mounting area and do not collide with wheels or fenders.
- DOT/FMVSS108 compliance: Reduces liability and ensures standard visibility and durability.
FAQs
- Are submersible trailer lights legal for all trailers? Yes, if they meet DOT/FMVSS108 requirements and are properly wired.
- Will these lights work in saltwater environments? Many are designed for marine exposure, but confirm corrosion resistance and seals for saltwater use.
- What maintenance is needed for submersible lights? Periodic inspection of seals, gaskets, and wiring connections; replace damaged lenses promptly.
- How do I choose between IP68 and IP67 ratings? IP68 provides deeper immersion protection; IP67 is water intrusion protection during immersion but may be less durable over time in heavy submersion.
- Do these lights require professional installation? Some kits are straightforward, but for trailer wiring upgrades or license plate illumination, professional installation is recommended if you’re unsure.
- What width should I consider for trailer lights? Choose lights sized to match or exceed the trailer width and ensure proper clearance on both sides.
