Buying Guide: Key Considerations For Sealed Trailer Lights
What should you check before buying? Look for IP ratings (IP68 is ideal for fully submersible use), DOT/SAE compliance, and the type of mounting (surface vs. recessed). Consider the length of the wiring harness, ease of installation, and whether the kit includes license plate illumination if required for your trailer class. For boat trailers, prioritize submersibility and corrosion resistance. If you need a universal kit for multiple trailer types, choose a model with a longer harness and compatible mounting hardware.
Waterproofing And Submersion
Submersible lights are designed to resist water ingress and corrosion. Look for full sealing methods such as sonic welding or gasketed lens edges. Drain holes can help remove trapped water after immersion, extending LED life over time.
Compliance And Safety
DOT FMVSS108 or SAE standards indicate visibility and reliability. Compliance reduces liability risk and improves compatibility with other vehicle lighting systems. Always confirm that the selected kit matches your trailer’s width and mounting pattern.
Installation And Maintenance
Choose kits with included hardware and color-coded wiring. A longer wiring harness simplifies wiring on larger trailers. Regularly inspect grommets and seals, especially in marine environments where saltwater can accelerate wear.
Durability And Materials
Look for corrosion-resistant housings (stainless steel hardware, ABS or molded plastic bodies) and high-quality LEDs with long lifespans. Submersible units often use acrylic lenses that resist cracking under impact and salt exposure.
